Shipping Label Guide for Australian Small Business

Shipping labels are the first thing your carrier scans and the last thing your customer sees before opening their parcel. Getting them right saves time, cuts errors and keeps your despatch running smoothly. This guide covers label formats, printer options and platform integrations for Australian small businesses.

Standard Shipping Label Sizes

Australian carriers accept two main label sizes:

• 100 x 150 mm (4" x 6"): the standard for Australia Post, Sendle, StarTrack and most domestic carriers. Fits satchels, boxes and bags. This is the size you'll use 90% of the time.
• 100 x 200 mm (4" x 8"): used for large or heavy parcels that need extra information, including dangerous goods declarations and multi-leg routing. StarTrack and some freight carriers prefer this size for palletised shipments.

Stick with 100 x 150 mm labels unless your carrier specifically requires the larger format. It's the universal standard and every major platform supports it.

Direct Thermal vs Pre-Printed Labels

There are two main approaches to printing shipping labels, and the right one depends on your volume.

Direct Thermal Printing

A dedicated thermal printer uses heat-sensitive label stock. There's no ink, no toner and no ribbon. You load a roll of blank labels, hit print and get a crisp barcode label in under two seconds. Running costs are low because the labels themselves are the only consumable.

Direct thermal labels can fade if left in direct sunlight for extended periods. For domestic parcels that spend a few days in transit, this isn't a problem. For long-term warehouse storage labels, consider laminated alternatives.

Printing on A4 and Cutting

You can print shipping labels on A4 paper or A4 sheet labels using a standard inkjet or laser printer. This works for low-volume sellers doing fewer than 10 parcels a day. Beyond that, the time spent cutting and peeling adds up fast. You'll also spend more on ink and label sheets per label compared to thermal rolls.

Cost Comparison

At 20 parcels a day, switching from A4 sheets to thermal roll labels saves roughly $50 to $80 per month in consumables alone, not counting the time saved.

Recommended Shipping Label Printers

Dymo LabelWriter 5XL

The Dymo LabelWriter 5XL is the go-to shipping label printer for Australian small businesses. It prints 100 x 150 mm labels at 300 dpi with sharp, scannable barcodes. USB connectivity and native support in Dymo Connect software make setup straightforward. It handles rolls of up to 220 labels, so you won't be swapping rolls constantly during a busy despatch session.

Brother QL-1110NWB

The Brother QL-1110NWB prints labels up to 103 mm wide and connects via USB, Wi-Fi and Bluetooth. The wireless connectivity is handy for shared warehouse setups where multiple staff need to print from different workstations. It uses Brother's DK label rolls, which are available in die-cut and continuous formats.

Carrier and Platform Integration

Your shipping label printer needs to work with your sales platform and carrier. Here's what to expect:

• Shopify: generates 100 x 150 mm PDF labels for Australia Post and Sendle. Print directly from the orders page. Works with both Dymo and Brother printers via their desktop software.
• WooCommerce: use the Australia Post or Sendle plugin to generate labels from the WordPress dashboard. Export as PDF and print to your thermal printer.
• eBay Australia: built-in label printing through the eBay postage tool. Supports Australia Post and Sendle. Prints to any connected printer, including thermal label printers.
• StarTrack: use the StarTrack Online portal or integrate via API. Labels are generated as 100 x 150 mm or 100 x 200 mm PDFs depending on service type.

Most platforms output labels as PDF files. Set your thermal printer as the default and configure the page size to match your label stock (100 x 150 mm). This avoids scaling issues that cause barcodes to print too small to scan.

Tips for Clean, Scannable Labels

• Print at 300 dpi or higher. Lower resolutions produce fuzzy barcodes that carriers' scanners struggle to read.
• Avoid scaling. Print labels at 100% size. Don't let your PDF viewer "fit to page" as this shrinks the barcode.
• Use quality label stock. Cheap thermal labels can jam, curl or fade. Stick with genuine Dymo or Brother rolls, or reputable compatible brands.
• Store labels correctly. Keep thermal label rolls in a cool, dark place. Heat and sunlight degrade the thermal coating before you even print.
• Clean the print head. Wipe the thermal print head with isopropyl alcohol every 500 labels to maintain print quality.
