Australia is one of the other countries taking part in this year’s online shopping festival. For companies already riding a wave of increasing Chinese demand, the chance to be seen by millions of consumers is laying the ground work for future trade.

The preparations inside one of Chemist Warehouse’s Sydney stores for another day of trading - paled in comparison to the work that’s been done for one massive day in China.

"We’ve been preparing a lot in advance since July, stocks in the warehouse we are really excited," said Elias Wehbe, managing partner of Chemist Warehouse.

The vitamin and health supplement seller is one of several Australian companies participating in China’s online shopping festival this year.It’s fully aware of the opportunity that exists in a country that has been part of its overseas strategy for a couple of years.In 2015, Chemist Warehouse joined online retail platform Tmall.

"Last year with relatively small preparation, we only signed the agreement for Tmall in September, and we were open on their website on the first of November with only 53 products we made some incredible stats over there - we managed to hit 1 million rmb 3 minutes and 10 million rmb in 43 minutes," Wehbe said.

Those sales have been fuelled by an increased demand for Australian health supplements - beginning with the suitcase trade - Chinese consumers stocking up in Australian stores and sending goods back home. That trend progressed to an explosion of daigous across Australia - people creating small businesses to handle that overseas demand which has grown into a billion dollar industry.

Now many of those Australian companies have developed their own strategies for direct trade into China.

"Australia has a very good brand name in we are regarded as a clean economy, a healthy economy, our food stuffs are very highly regarded, our pharmaceuticals, our vitamins ect, they are very highly regarded, they are regarded by Chinese consumers as being top quality goods," said Marcus Rubenstein, founder of Red Door.

Which is why Chemist Warehouse managing partner Elias Wehbe says the preparation is vital.

"We do want to make sure our stock is strategically selected with our suppliers, the stocks available," Wehbe said.

For a unique day of sales and exposure to a growing market - that shows no signs of slowing.
