eBay Australia has revealed plans to more than double its fees on some auction listings, effectively penalising non-professional sellers.

The days of eBay as largely an online garage sale are finished as the company pushes sellers away from second-hand auctions towards listing new items in the fixed price format and on eBay Stores.

But as consumers and mum and dad sellers typically run one-off auctions as opposed to opening their own stores or setting a fixed price, they appear to be left worse off by the upcoming changes. 

From September 22, eBay Australia will scrap insertion fees for the first 30 items listed for auction in a month. Insertion fees currently range from $0.30 to $3.50 for most items (excluding vehicles).

However, final value fees will increase from 5.25 per cent to 7.9 per cent, capped at $49.95 for each of the first 30 listings per month. This is now the same as the final value fee paid by professional sellers with eBay Stores.
