Australia Post is generally very good — better than the private alternatives. But it’s not perfect.
What could be better?
More transparency — or ease of use — on the pricing. It’s difficult and complicated finding out how much a shipment costs. On your website, include a list of common items, their weights, dimensions and estimated postage costs. Examples of these could be CD’s, books, laptops, clothes.
Include insurance, registration options.
Businesses and eBay sellers are your best friends. Find out what they ship. Make it easy for them to find the shipment information on your website.
If you don’t already, start selling package material and stamps on your website. Make it obvious where these are located on your website.
