During last year's Singles Day sales event, Australia ranked third in terms of selling to China by gross merchandise volume, behind Japan and the United States.
Sales hit the $1 billion mark in the first minute and eight seconds, Alibaba said.
China's biggest online shopping festival, Singles' Day, got underway at Sunday midnight local time, with e-commerce giant Alibaba saying 91.2 billion yuan ($13 billion) worth of goods were sold in the first hour, compared with 69 billion yuan past year.
Originally conceived by young people celebrating the joy of being single, November 11 (11.11. - each digit representing a single person) has evolved into a huge shopping event, with Chinese e-commerce giant Alibaba particularly successful in marketing the occasion.
US market research company Forrester said total combined e-commerce sales by all USA platforms on Black Friday and Cyber Monday in 2018 hit $14.2 billion, which was just 46 percent of Alibaba's total in that year.
This year, more than 200,000 brands are participating, Alibaba said.
Alibiba's Singles Day isn't just an online shopping festival but also a high-on-glamour affair.
Alibaba anticipates 500 million shoppers will take part in the 11.11 event this year, up from about 100 million recorded last year. Last year, an estimated 1 billion packages shipped as a result of "Singles Day" purchases, according to Reuters. "Singles' Day really kicks off the busy period for NZ Post".
For this year's Singles' Day, Forrester forecasts Alibaba will generate $37 billion in GMV, or a 20.5% jump compared to 2018. Previous year we delivered over 14.5 million parcels during November and December.
Chinese consumers will spend 54% more this year than in 2018, but 78% said they would think twice about buying US products due to loyalty to their country, AlixPartners found in a recent survey of more than 2,000 Chinese consumers.
