Australian shoppers will get their own version of America's online shopping phenomenon, Cyber Monday, when some retailers cut their online prices for 24 hours next month.

Australia's take on the online sale, called Click Frenzy, will actually begin on a Tuesday (November 20) rather than a Monday, and is expected to boost sluggish retail sales before Christmas. ''We're likening it to ''the Boxing Day sales on digital steroids,'' said organiser, Grant Arnott, from Power Retail, a service for online and multi-channel retailers.

In America, Cyber Monday, launched in 2006, has online sales from more than 700 retailers, and attracts 10 million shoppers. Last year, they spent $US1.25 billion ($1.22 billion) during the 24-hour sale.

Held on the Monday after Thanksgiving, Cyber Monday was started so online retailers could capitalise on Black Friday - the day after Thanksgiving and the biggest day of the year for US shops.

It is now the biggest day for online sales in America and Mr Arnott hopes Click Frenzy will achieve the same result in Australia. He expects up to 200 retailers to take part and hopes to drive ''tens of millions'' of dollars of sales.

National Retail Association executive director, Trevor Evans, welcomed the idea on the back of ''really bad'' retail trade figures but feared international retailers could rob local shops of pre-Christmas sales.
