New figures show online shopping jumped sharply in the lead up to Christmas.
The NAB Online Retail Sales Index shows online sales jumped 27 per cent in November, with many customers doing their shopping early to allow time for deliveries.
When compared to November 2011, the amount of online shopping was only marginally higher.
NAB chief economist Alan Oster says online shopping only accounts for around 6 per cent of total retail spending, so the growth is coming off a low base.
"You shouldn't just look at online and say one is replacing the other.
I think it is encouraging," he said.
