Record sales predicted for Boxing Day

Aussie shoppers are tipped to splurge more on Boxing Day than in previous years, largely due to record low interest rates.

The National Retail Association is predicting people will shell out about $2.28 billion on Monday, the highest Boxing Day spend in Australian retail history.

NRA chief executive Dominique Lamb said shoppers taking advantage of the post-Christmas sales were expected to spend $100 million or 4.2 per cent more than they did on Boxing Day last year.

"Consumer spending has become much easier based on the fact that the RBA (Reserve Bank of Australia) has kept interest rates at a record low," Ms Lamb told reporters in Sydney on Saturday.

"We've also seen an increase in consumer confidence; Commonwealth Bank is predicting that this (month) is a seven-and-a-half-year high on consumer spending for December."

The RBA left interest rates on hold at an all-time low of 1.5 per cent earlier this month.

Queenslander retailers in particular are tipped to enjoy the largest increase in Boxing Day spending, with the NRA predicting them to take in $390 million, a six per cent boost on last year.

Group general manager at Westfield John Warn said a record two million shoppers were expected to visit Westfield stores on December 26.

"That will mean that almost one-in-ten Australians will be visiting a Westfield centre on Boxing Day," he told reporters.

Christmas Eve sales figures should be slightly more modest, with shoppers around the country tipped to spend $1.6 billion on Saturday.

While Sydney's Pitt Street Mall was subdued on Saturday, the Sydney Fish Markets was on track to eclipse 100,000 customers during its 36-hour pre-Christmas trading marathon.
