Amazon Australia is tipped to launch within days, but products have started to appear on the site.
Eighty computer products from HP are now displaying in the search results.
Even though on the front page Amazon.com.au is still showing as a shopfront for just books, a search query, reported by esellercafe.com and verified by Business Insider, brings up five pages of HP products.
The results include notebook computers, printers, printer refills, keyboards, dongles, networking equipment and monitors -- although none can be clicked through to place into the shopping basket.
Every item shows that one merchant is offering the product for sale, but the link to find out who the seller is leads nowhere. The items are also categorised as "any category", as opposed to a "Computers & Tablets" category.
While the Amazon.com.au website has operated for years, it has been an online shopfront for the US parent company. Business Insider confirmed in April that Amazon was setting up a full-scale operation in Australia.
On Monday, hundreds of Australian merchants attended a seminar in Sydney to hear from Amazon executives that both a third-party marketplace and Amazon-native platforms would be available upon launch – although the launch date was still kept a secret.
Australian retailers will pay $49.95 plus GST each month to sell on Amazon, plus 6% to 15% of each item sold.
Industry analysts have predicted Amazon Australia would start trading before November 24, which is a big sales day known in the US as Black Friday. Business Insider reported last week that the sales system itself is ready to go, and the fulfillment centre in Melbourne has been welcoming employees at least since the end of October.
Last week, Lifehacker reported Reddit users were finding power boards, cables and other electronic accessories listed on the Australian site.
An Amazon spokesperson told Business Insider last month that Dandenong South, in Melbourne’s south-eastern suburbs, was selected as the location for the first fulfillment centre without any government funding or tax rebates.
"The site is an excellent fit for Amazon’s requirements – great location, good infrastructure, excellent source of talent – we are excited to be opening our first Australian fulfilment centre in this location," said the spokesperson.
