Amazon Australia has hit 10,000 sellers on its Australian marketplace since launching in December.
According to an article by data analytics firm Marketplace Pulse, this has doubled in size from 5,000 sellers in January.
The firm attributes the rise to a change in policy, with Amazon initially requiring approval to sell on its platform.
The move has increased the share of sellers shipping from China to more than half.
Marketplace Pulse data indicates 70 new sellers join in Australia every day, with more than 50,000 sellers expected by the end of the year.
