Got some leftover gift cards from Christmas and not sure what to spend it on?

An Australian model has revealed an amazing “life hack” for those looking to spend them.

Taking to TikTok, Alex Davidson explained that many gift cards don’t have to be used within the shopping centre that issued them.

“I feel like this is a life hack so imma share,” she wrote in the caption.

Davidson revealed the cards can be used anywhere that has EFTPOS, not just at the shopping centre they came from.

Which means you can use Westfield gift cards to pay for petrol.

She came across the revelation after an employer tried to pay her in gift cards and told her they could be used outside the centre.

“They’re actually just EFTPOS gift cards,” she said.

“Most shopping centres just label the cards themselves with their logo or shopping centre names, but it’s usually like an EFTPOS gift card.

“I just thought I’d let you all know that when people are giving you gift cards for shopping centres as a whole, it’s kind of annoying, I don’t really enjoy that.

“But they’re literally an EFTPOS gift card, it is not just for the shopping centres.”

The video has been viewed over 230,000 times with workers jumping in the comments to confirm the news.

“I actually tell this to all my customers, you are very correct. It’s just an EFTPOS card,” one person said.

“I work in a shopping centre that’s not Westfield but I let people use their Westfield cards all the time,” another added.

Others called it “so smart” and said their “mind is blown” while some said the hack didn’t work for them.

“I tried this and they said no,” a TikTok user replied.

On Westfield’s website, they confirm that the hack is correct.

The shopping centre states their cards are “redeemable at participating retailers in Australia with EFTPOS facilities.

“For this reason, we do not feature a definitive list of retailers outside of Westfield on our website for our card – It will work in the same capacity as an everyday debit card,” he said.

“Gift Card acceptance is at the retailer’s discretion and some retailers may choose not to accept the Westfield Gift Card.”
