Smart shipping starts here – learn how to pack, price, and send your parcels for less in 2025

With rising logistics costs and increasing pressure to deliver quickly and affordably, finding the cheapest way to ship a package has never been more important – especially for Aussie businesses navigating a competitive 2025 landscape. No matter if you're a small eCommerce brand fulfilling customer orders or a large operation managing bulk dispatches, every dollar saved on shipping adds up.

You need to remember that cutting costs doesn’t mean compromising on quality, either. The secret lies in smart decisions – from selecting the right courier service to choosing the most efficient mailing boxes. The good news? With a bit of know-how and the right packaging partner, you can significantly reduce your expenses while ensuring your parcels arrive securely and professionally.

In this guide, we’ll walk you through the best courier options, explain how Australia Post shipping prices compare to alternatives, and show how premium, lightweight packaging boxes from Ozpack can help you save money and time – without cutting corners.

Understanding Your Shipping Options

When it comes to shipping within Australia, businesses have more options than ever before. The challenge is finding a provider that balances cost, reliability, and convenience. To work out the cheapest way to ship a package, it's important to understand how each carrier stacks up in 2025.

Australia Post

Still the most widely used postal service in the country, Australia Post shipping prices vary based on weight, size, and delivery speed. For smaller items or letters, AusPost can be quite economical.

However, once you start sending heavier or bulkier parcels, costs can rise quickly. Comparing Aus Post shipping prices for regular parcel post and express delivery gives businesses a clearer picture of their true expenses.

Sendle

A favourite among eCommerce sellers, Sendle offers competitive flat-rate pricing and door-to-door delivery. For many metro-to-metro routes, it often beats AusPost in price, especially for packages under 25kg.

CouriersPlease and Aramex

These are solid options for businesses sending high volumes of parcels. While not always the lowest cost for smaller items, their strength lies in offering negotiated business rates, fast metro delivery, and real-time tracking.

Top Tip

Don’t stick with one provider. Use shipping aggregators or tools that compare live courier rates based on destination, weight, and size – this alone can cut costs by 10–20%.

How Packaging Affects Shipping Costs

Choosing the right packaging isn’t just about protecting your product – it’s one of the biggest factors in determining how much you'll pay for shipping. Courier companies calculate costs based on weight and cubic volume. That means oversized or poorly packed items can rack up charges fast, even if they’re lightweight.

The Importance of Right-Sized Mailing Boxes

Using appropriately sized mailing boxes helps reduce wasted space, avoid dimensional weight charges, and present a more professional parcel. For instance, instead of using a satchel for fragile items, consider a sturdy mailing box that offers better protection while keeping dimensions compact.

Some great options include:

●      310 x 230 x 105mm Die Cut Mailing Box – ideal for medium-sized products like books, skincare, or tech accessories.

●      174 x 128 x 53mm Die Cut Mailing Box – a smart choice for smaller items or gift sets.

●      270 x 200 x 95mm Black Mailing Box – sleek, strong, and great for brand-conscious businesses.

All these options are made from premium-quality, lightweight corrugated cardboard – a material specifically chosen to save on postage while maintaining structural integrity. Plus, they’re made from 100% recycled cardboard, making them an eco-conscious choice.

Why Weight Matters

Heavier packaging means higher base shipping costs. That's why opting for lightweight, high-strength packaging boxes is important. At Ozpack, our entire range of mailing boxes is designed with postage savings in mind, helping you stay lean on logistics.

Choosing the Right Mailing Box for Your Product

No two products are the same – and neither should their packaging be. Selecting the correct mailing box makes sure your items arrive safely, look professional, and ship as affordably as possible.

Match the Box to the Item

Here’s a simple guide to choosing the right size and style of mailing boxes based on what you’re sending: 

●      Jewellery or Accessories – Opt for compact options like the 174 x 128 x 53mm Die Cut Box. These boxes keep small, delicate items snug and safe.

●      Books or Apparel – Medium-sized options such as the 310 x 230 x 105mm Mailing Box offer enough room without unnecessary bulk.

●      Luxury or Gift Items – Create a premium unboxing experience with our sleek Black 270 x 200 x 95mm Box.

By choosing the most efficient mailing boxes Australia has to offer – specifically those made with lightweight, premium corrugated cardboard, you reduce postage costs and increase customer satisfaction.

Die-Cut for a Perfect Fit

Die-cut mailing boxes offer a form-fitting design that minimises movement inside the box, reducing the need for excess filler materials. This not only protects the contents but keeps dimensions streamlined – saving you on postage.

Ozpack’s full range of mailing box sizes means you can tailor your packaging to fit just about anything, whether you're shipping candles, cosmetics, books, or bulkier items.

Tips to Minimise Costs and Maximise Value

When you’re looking at cutting shipping costs, every small detail adds up. Beyond choosing affordable couriers and right-sized mailing boxes, these practical tips can help you get the most value from every parcel sent.

1. Use Lightweight, Durable Packaging

Avoid overpaying on postage by switching to premium, lightweight corrugated cardboard boxes – like those in our Ozpack range. Our materials are designed to be strong without adding extra grams to your shipping bill.

2. Choose the Right Size

Selecting the right mailing box isn’t just about protection – it’s about efficiency. An oversized box means higher Australia Post shipping prices due to cubic weight. Keep packaging snug and minimal.

3. Buy in Bulk and Save

If you're sending parcels regularly, purchasing mailing boxes in bulk can reduce your per-unit cost. Ozpack offers wholesale pricing and consistent supply across Australia.

4. Reuse and Recycle

Our boxes are made from 100% recycled cardboard and designed to be reused. This not only reduces environmental impact but can also become part of your brand's sustainability messaging.

When it comes to shipping products, ensuring they arrive safely and in perfect condition is essential. Whether you're sending fragile items, electronics, or documents, choosing the right packaging can make all the difference. Padded mailers have quickly become a go-to solution for businesses looking to protect their shipments while also keeping costs and environmental impact low.

What Are Padded Mailers?

Padded mailers are lightweight envelopes lined with protective cushioning materials, such as bubble wrap or foam, designed to absorb shock and prevent damage during transit. They are available in various sizes, making them versatile for a wide range of shipping needs. Their outer shell, typically made from durable paper or plastic, offers additional protection from external elements like moisture and dust.

The Key Benefits of Padded Mailers

1. Superior Protection
   

   The most obvious advantage of padded mailers is the protection they provide. The internal padding helps cushion items against rough handling, drops, and impacts, ensuring they arrive intact. This is particularly important when shipping delicate or valuable goods such as jewellery, electronics, or glass items.

2. Cost-Effective
   

   Shipping costs are a major concern for any business, and padded mailers offer a budget-friendly solution. Unlike bulky boxes, padded mailers take up less space, reducing the weight and volume of your shipments. This can significantly lower shipping fees, especially when mailing lightweight or medium-sized items.

3. Eco-Friendly Options
   

   As businesses move toward more sustainable practices, the demand for eco-friendly packaging has risen. Many padded mailers are now made from recyclable or biodegradable materials, helping reduce plastic waste. Some options, like kraft paper mailers, offer both protection and environmental benefits, providing a sustainable alternative to traditional plastic packaging.

4. Easy to Use
   

   One of the key advantages of padded mailers is their convenience. These mailers typically come with self-sealing adhesive strips, making them quick and easy to close. This can save time and effort when packing multiple shipments. Additionally, their lightweight design makes handling and storage more efficient.

5. Space-Saving
   

   Padded mailers take up far less space than bulky boxes, both during storage and shipping. This can be a crucial factor for businesses that need to keep shipping materials on hand without occupying valuable storage space. They are also more compact and stackable, making warehouse organisation much simpler.

6. Customisation Options
   

   Custom branding is a great way to leave a lasting impression on customers. Padded mailers can be printed with your logo, company name, or marketing messages, adding a professional touch to your deliveries. With custom padded mailers, you not only protect your shipments but also enhance your brand visibility.

When Should You Use Padded Mailers?

Padded mailers are ideal for items that require moderate protection during shipping but do not need the rigidity of a box. They are perfect for:

• Books:

  The padded lining ensures that book covers and pages remain unbent and protected from moisture.

• Jewellery:

  Lightweight and delicate items, such as necklaces or rings, benefit from the cushioning provided by padded mailers.

• Documents:

  Important papers or contracts can be shipped securely without worry of damage or creases.

• Electronics:

  Small gadgets, like mobile phones or headphones, are well-suited for padded mailers due to the shock absorption properties.

In today's world, sustainability has become more than just a buzzword—it’s a necessity. As the harmful effects of plastic waste continue to grow, businesses and consumers alike are seeking alternatives that reduce environmental impact without compromising on convenience. One area where we can make a significant difference is through the use of sustainable zip lock packaging.

Why Traditional Zip Lock Bags are a Problem

Conventional plastic zip lock bags, while convenient, are typically made from petroleum-based materials. These plastics can take hundreds of years to decompose, contributing to the overwhelming plastic pollution crisis in our oceans and landfills. As the demand for single-use packaging grows, so does the volume of plastic waste.

The good news? There are now eco-friendly alternatives that offer the same functionality without the environmental cost.

The Rise of Sustainable Zip Lock Packaging

Sustainable zip lock bags are designed to offer an eco-conscious solution, utilising materials that are either biodegradable, recyclable, or reusable. These products provide a simple way to reduce plastic waste while still enjoying the convenience of traditional zip lock bags. Here are some of the most popular sustainable options:

Recyclable Zip Lock Bags: Unlike traditional plastic bags, these are made from materials that can be recycled at the end of their life cycle. Look for bags made from low-density polyethylene (LDPE), which can often be recycled through specialised facilities.

Biodegradable and Compostable Bags: These bags break down naturally over time, leaving no harmful residues. Typically made from plant-based materials like corn starch, they offer a zero-waste alternative to traditional plastic.

Reusable Zip Lock Bags: Made from durable materials such as silicone or reinforced polyethylene, these bags can be washed and reused multiple times, drastically cutting down the need for single-use plastics.

How to Make the Switch

Transitioning to sustainable zip lock packaging is easier than you might think. Here are a few tips to help you get started:

Assess Your Needs: Start by identifying where you currently use single-use zip lock bags. This could be in your kitchen, office, or even for packaging products in your business. Once you know where the most waste is being generated, you can look for sustainable alternatives that fit these specific needs.

Choose the Right Materials: Not all sustainable bags are created equal. If you're looking for a zero-waste option, compostable bags are the way to go. If durability and reusability are your priorities, then silicone or reinforced reusable bags are ideal.

Support Responsible Brands: Look for companies that prioritise sustainable practices in their manufacturing processes. Brands offering biodegradable, recyclable, and reusable options are becoming more accessible, and by supporting them, you contribute to the growing demand for eco-friendly products.

Dispose of Bags Correctly: Even when using recyclable or biodegradable zip lock bags, proper disposal is key to ensuring they don’t end up in landfill. Check your local recycling programs to see how best to dispose of these materials, and always ensure compostable bags are placed in the appropriate waste stream.

Small Changes, Big Impact

Switching to sustainable zip lock packaging might seem like a small change, but when you consider the sheer number of plastic bags used globally each year, the impact can be enormous. By choosing alternatives that reduce plastic waste, we not only help protect our environment but also encourage others to make more eco-conscious choices in their daily lives.

At Ozpack, we believe in providing eco-friendly packaging solutions that offer functionality without compromising our planet. By making the switch to sustainable zip lock bags, you can do your part in reducing plastic waste and supporting a greener future.

Choosing the right packaging supplier is essential if you want your business to be successful.  Whether you’re a small business choosing your first supplier, or whether you’re a large organization looking to change who you order your materials from, finding someone who can meet your requirements can be daunting. One way for you to make things easier on yourself would be for you to ask the right questions, so you can get the answers you’re looking for.

How Large is the Product Range?

It’s important to make sure that your supplier has a large product range that's consistent in quality. Do they offer everything you need to consolidate the suppliers you go through? How often are their products restocked? Are they able to source different sizes should you need them? Having a good understanding of what you can get, and what you need is key if you want to find the right supplier. When asking this question, be sure to avoid companies that have limited ranges, who aren’t willing to advise you, or who clearly have variations in quality across different product lines.

When you come to us at Ozpack, you’ll notice that we have our own warehouse with stock levels updated daily. We also have new shipments coming in every week, to ensure that our commercial clients always have access to the packaging materials they need. 

What Experience Does the Supplier Have?

You also need to ask the supplier how experienced they are. You need someone who can recommend the right packaging, as well as someone who understands the industry you work in. They should understand the challenges you’re facing, and the pain points you’re trying to overcome. If you can ensure this, you can expect cost-effective solutions that tick all of the right boxes. 

We’re proud to say we’re one of the most reliable packaging suppliers in the business. We can provide everything from mailing sachets to padded envelopes and cartons, so as your business scales, you can count on us to keep up with your current demand, as well as any new product lines you may go on to explore.

What’s the Cost of Shipping?

Pricing is so important when choosing a packaging supplier. Make sure you take into account soft costs and don’t compromise quality. Even if it results in a cheaper deal for you, your customers will be the ones who pay for it. When choosing a shipping supplier, avoid companies that have steep shipping costs, have excessive minimum orders, or don’t tell you clearly how much your delivery is going to cost.

We have our own manufacturing facility, which helps to keep our prices very competitive. We eliminate the middleman, which helps to reduce the cost significantly. As we are in full control over the manufacturing process, we also can ensure consistent quality across every single box, packet, and mailing wallet. 

What are the Shipping Terms?

Even if a company has a huge range of packaging supplies, that doesn’t mean that they’re going to provide you with what you need, when you need it. Even a slight delay in receiving your packaging materials could lead to a financial loss and lower customer satisfaction. When deciding which packaging supplier to go through, make sure that you're aware of the expected delivery times, and if they can send the products out within a reasonable timeframe. Avoid suppliers who don’t offer delivery timeframes, or who aren’t clear on their shipping terms.

Here at Ozpack, we are located in New South Wales. If you’re based here, we can offer you discounted shipping rates. You can also expect to receive your delivery in as little as 3 days, which means you will always have the materials you need to continue running your business at maximum efficiency. We also offer express delivery, and pick-up options, if you’re in the local area.

Do they Have Good Customer Service?

A crucial point to consider when choosing a packaging company is their customer service. You need to know what to expect in terms of their response time, and you also need to know if there are multiple ways to get in touch with the company.

We know how important it is for you to get the support you need if there is ever an issue. That’s why we offer an SMS number you can text: +61 483 948 100, along with an email address and a live chat option. We also have a social media page you can follow us on, which you can find here.

What’s the Company’s Reputation Like?

Online reviews are a key indicator in regards to how reputable a company is. Establishing trust and cultivating relationships takes both time and dedication. If a supplier is known as being reputable and if they have been in the business for a very long time then this is a good indicator that they can be trusted. Be sure to avoid companies with low reviews, or reviews that look to be fake.

Here at Ozpack, we understand how important it is for you to find someone who you can count on, and that’s why we will do everything we can to offer the packing materials you need, without compromise. We have been in the business for years and invested heavily in our products. That’s why you know you can trust us to provide you with the experience you’re looking for.

Do they Offer Sustainable Packaging?

The world we live in is very environmentally focused. The packaging products you use, reflect your brand, so it's important to stay ahead of the curve and to make sure that you have options regarding this. 

At Ozpack, we have a huge range of sustainable choices for you to choose from. This includes egg cartons, kraft paper, card mailers, and shipping bags, so you can count on us to provide anything you need. 

So as you can see, choosing the right packaging supplier can be difficult, but when you come to us, we have the ability to not only meet your expectations but also exceed them. We have years of experience, our own manufacturing facility, and plenty of environmentally friendly products to choose from. We also have the option of offering reduced shipping costs if you live in the New South Wales area, along with pick-up options if you’re in a hurry and don't want to wait for the courier.

With a focus on customer service, it’s no wonder we’re the top packaging supplier in Sydney.
