Scamwatch has urge shoppers to look out for fake websites which offer products at very discounted prices.

When a person makes a purchase from one of the sites, they receive a fake item, or no item at all.

Fake ads on classified websites are also on the rise, increasing by a staggering 50 per cent this year.

Australians are expected to spend $5 billion online on Friday, during the Black Friday online shopping bonanza.

Founder and CEO of the Retail Doctor Group, a consultancy firm for retailers, Brian Walker, says it’ll be a mammoth day.

“We expect anywhere up to around 13 million Australians to get online and have a bit of a look,” he said.

But Mr Walker says the bulk of Christmas gift shopping will still happen in bricks and mortar stores.

“Most of it will be in the physical stores. Online retail, certainly pre-COVID was an average of about 8 per cent of all sales,’ he said.

“With COVID, the vast bulk will still take place in the physical stores.”
