The peak retailing body is expecting billions of dollars will be spent over the Boxing Sales period, despite rising virus numbers causing more to isolate.
Australian Retailers Association is expecting a whopping $3.1 billion will be spent on Boxing Day with the biggest ticket items touted to be household goods, clothing and footwear.
ARA chief executive Paul Zahra said close to $21.1 billion will likely be spent over the post-Christmas sales period.
"Consumers can expect to see discounts across the board with retailers to slash their prices on a range of items from fashion to homewares and electronics,"
"While people have been purchasing gifts for others in the lead up to Christmas, the Boxing Day sales are traditionally a time when people purchase things for themselves or their homes."
The forecasts in conjunction with Roy Morgan are expecting the total sales number is an increase of 2.1 per cent compared to the prior year.
It also coincides with similar forecasts from Commonwealth Bank which is touting sales during the Boxing Day sales will exceed $4 billion.
In the ACT, sales growth over the period is anticipated to be 16.3 per cent compared to 2019 before the pandemic.
Nationally that figure is expected to be 12.6 per cent.
Despite the economic sugar hit to the retail sector, RateCity research director Sally Tindall flagged consumers should be weary of debt traps such as buy now, pay later and high usage of credit cards.
"Anyone using credit cards or buy now, pay later platforms in the sales need to be particularly careful not to spend more than they can afford to repay," Ms Tindall said.
Mr Zahra from the ARA noted the rise of Omicron and other COVID-19 cases would not deter from people hitting the shops, flagging retailers would be compliant with health rules.
"Sales are set to remain strong despite the ongoing threat of Omicron," he said.
"We're also asking customers to be patient. Retail staff will be fully stretched with so many people out in the shops at this busy time of year so it's an important reminder for people to shop respectfully."
