Rapid antigen tests (RAT) seem to be as rare as hen's teeth kits and right on cue, scammers have sprung into action with promises of 'special' supplies.

Scammers are working overtime on social media with claims that they can access bulk supplies. The result is that many Australians desperate to source RAT kits locally are ending up red-faced, poorer and empty handed.

A scam spreading on Facebook offers a 'bulk buy' of RAT kits if you pay in advance.

Are alarm bells sounding for you?

Kate Browne, personal finance expert at Finder, says: “With RAT kit shortages at an all-time high, Australians should be wary of any private offers to buy tests online.

“If the offer seems too good to be true, it probably is. Don’t give your personal information to anyone who approaches you online who you don’t know.

“Finding a RAT kit in a shop currently is like finding a needle in a haystack – your best bet is to shop online with reputable dealers."

If you see a scam operating, report it to www.scamwatch.gov.au and be sure to call it out online to protect others.

Have you managed to secure a RAT kit? Do you have any advice for other members on where to look?
