Consumers across the world pumped more than $US6 billion ($8 billion) into the retail sector, of which Australia played its part, during the frenzied shopping days known as Black Friday and extending into Cyber Monday. While it's an American tradition, it marks the start of the lead-up to the busy Christmas period in Australia and evidence suggests that more buyers are going online for bargains and convenience, which could force more discounting to entice shoppers back to traditional bricks and mortar shops. The Online Shopping industry has performed strongly over the past five years, with its continued popularity expected to boost industry revenue by 14.9% in 2016-17, to total $18.0 billion. Online sales growth has been supported by rising consumer confidence in online shopping, the large variety of good-value items available and further growth in internet use across the population. That rate of sales indicates that online spending is the equivalent to 7.3 per cent of spending at traditional bricks and mortar retailers as measured by the Australian Bureau of Statistics. Specialist retailers initially dominated online retailing, but e-commerce platforms are quickly becoming common for multichannel delivery.
