The secret lives of Aussie spenders: 1 in 4 hide money from partners

A wave of financial deceit is sweeping through Australian households, according to new research by Finder.
Â
A Finder survey of 1,017 respondents, 591 of whom are in a relationship, found more than 1 in 4 (27%) are secretly racking up debt, opening bank accounts, and even gambling money – all without their partner's knowledge.
Â
The research found 1 in 10 (10%) have secretly accumulated debt via a credit card or personal loan, while 9% have opened a bank account or credit card in their name only.
Â
The same proportion (9%) confessed to gambling in secret.
Â
Other covert money moves include financially helping out a family member or friend without disclosure (8%), making a significant purchase like a car or luxury item (7%), investing or selling investments without discussion (6%), and even withdrawing large sums from a joint account (4%).
Â
Sarah Megginson, personal finance expert at Finder, said the widespread level of deception amongst partners is worrying.
Â
"Keeping financial secrets from your partner can be just as damaging as emotional or physical betrayal when it comes to breaking trust.
Â
"This type of behaviour can create financial chaos, wreck your credit, and in some cases, lead to relationship breakdowns. Money is a deeply emotional topic and secrecy only compounds that.
Â
"Especially if you are in a longer-term relationship, their money might be yours – and vice-versa – in the event that you decide to go your separate ways."
Â
Megginson said that while some might justify secretive spending or financial decisions as harmless, the long-term consequences can be serious.
Â
"Whether it's hiding debt, secretly punting thousands on the ponies or investing joint money without your partner's input, these actions can spiral.
Â
"You might think you're shielding your partner, but you're actually adding risks to your future together.
Â
"Love is first and foremost about trust. Open conversations about money – the good, the bad, and the ugly – are the only way to build financial intimacy and security."
Â
Megginson said sometimes, secret spending and hiding purchases can be a sign of financial abuse, and urged anyone who feels like their partner controls their spending to seek help.
Â
"You can speak to a financial counsellor at the National Debt Helpline for free – their services are confidential and they can help you create a plan to move forward if you're stuck in a difficult financial situation.
Â
"Create a safe space for discussing finances regularly and be upfront about both individual and joint goals.
Â
"If you're scared to tell your partner about a money decision, it's a sign something deeper might be wrong – either with your financial habits or the relationship itself."
