Australians spent $12.6 billion on online shopping in the year to November with a surge in the final month as shoppers left adequate time for Christmas deliveries.
The National Australia Bank Retail Sales Index shows that in the 12 months to November 2012 online retail sales grew 27 per cent, compared to the previous year.
Online retail in the year to November was 5.7 per cent of traditional bricks and mortar retail sales.
Growth in online sales continues to outperform that of traditional retail, which increased by 2.6 per cent year-on-year in October.
The research also shows that online sales surged in November with the growth rate increasing from 26 per cent, year-on-year, in October.
NAB chief economist Alan Oster said traditionally November is the peak month for online sales as consumers like to allow adequate time for the delivery of their Christmas presents.
As a result in the previous two years there had been a decline in online sales in December.
However, he said as the online retail market matures it would be interesting to see whether consumers have had greater confidence to make online purchases closer to Christmas during 2012.
Mr Oster has also said that with more domestic retailers now having websites and guaranteeing goods will be delivered for Christmas if bought up to a week before, the online shopping spike may come later in 2012 than previous years.
