The Australian ecommerce market is expected to see another year of double-digit growth in 2011 with domestic retailers accounting for the majority of the activity, according to eBay.com.au and PayPal.

As a result, eBay.com.au will be seeing changes to the website between March and May to meet this growth.

Over the coming weeks and months, eBay will introduce changes to the search, buying and selling formats on eBay.com.au.

From early April 2011, eligible sellers listing auctions starting at 99c will get insertion fees free for up to 15 items per month. With no up-front fees to list, that means if vendors don’t sell, they don’t pay.

There will also be new mandatory inclusions for handling time and returns 

“Handling time and returns policies are not always clearly stated in listings, which can create confusion for buyers. As a result, from May 2011, all sellers on eBay.com.au must specify a handling time and a returns policy in their listings,” the company said in a statement.

Additionally, Best Match, eBay’s default sort order for search results, is being optimised to help buyers to find the most relevant listings from sellers who offer the best service, value and products.

eBay will be making price changes to the Movies, TV Shows and Games categories, as well as to all eBay Store levels in April 2011.
