Amazon Marketplace, an e-commerce platform owned by Amazon.com enables third-party sellers to sell new or used products alongside Amazon's regular offerings, launched in 2000.
Sales from Amazon Marketplace now represent over 50 per cent of all items sold globally on Amazon.
Russell Zimmerman, executive director of the Australian Retailers Association, said practical advice discussed at the event had been "extremely" insightful for retailers and businesses in attendance.
"Amazon's entry into Australia provides a great opportunity for local retailers to grow their customer base and increase sales," Zimmerman said.
"It's time to embrace change and get excited about the future."
Retail consultant Chris Wilkinson said a number of New Zealand retailers had attended the event, including some well-known retail chains.
"The Summit was the first opportunity for New Zealand businesses to see the collective interest from across the retail and wholesale sector in participation," Wilkinson said. "Unlike many of the large retail chains, Amazon is agile and can be responsive through leveraging technology and the resources of its overseas fulfilment solutions.
"To be successful going forward, big retailers need to emulate this kind of culture and adaptability within their own organisations if they are to be successful."
