Cassie Crofts became a private investigator two years ago and revealed the money detail that exposes cheaters.
A private investigator has revealed the surprisingly low-tech way that Aussies have been busted cheating on their partners.
Cassie Crofts has been catching cheaters for the last two years and said her industry has been aided by new-age devices and technological advancements that track and record people’s movements without them even knowing.
It’s not James Bond-level equipment, but digital bank statements, Alexa home assistants, and text messages that can reveal if someone is doing the dirty on their loved ones.
But the Queensland-based PI told Yahoo Lifestyle about an old-school sign that someone isn’t being faithful: cash.
“We’ve seen a lot recently, as it gets rarer and rarer to pay cash,” she said.
“If your partner normally does everything on Apple Pay and then suddenly he’s carrying around cash… potentially, that’s so they can buy some fancy dinners and that don’t show up on the bank account.”
Cash has been on the decline in recent years as Aussies find it easier to use their cards or digital wallets on their phones.
There has even been speculation that Australia would become a fully cashless society in a few years.
But cash has been making a comeback.
RBA data found that only 13 per cent of transactions were cash in 2022, but that lifted to 15 per cent in 2025.
So if your partner starts carrying cash, they could just be hopping on this new trend, or there could be something else at play.
