Singletons looking for love ahead of Valentine's day have been warned to beware of scammers.
In particular, people need to be alert to overseas romance scams and predators posing as genuine partners.
Consumers making last-minute jewellery purchases should also be aware.
NSW Fair Trading Commissioner Rod Stowe said there were 72 inquiries and 93 complaints about introduction agencies last year.
In 2011, lonely hearts were scammed out of $21 million, according to the Australian Competition and Consumer Commission.
Mr Stowe advised consumers to get introduction agency agreements in writing and to be wary of additional costs and ongoing requests for money.
"Once you're on the hook, a scammer will reel you in as long as you take the bait," Mr Stowe said.
Under Australian law, consumers can claim compensation if an introduction agency fails to meet a guarantee.
"People may be able to claim compensation for their costs in time and money when something goes wrong with a service," Mr Stowe said.
"Last-minute buys and the allure of the romantic can catch out the unwary and trusting.
"You should know you are entitled to get what you paid for and not be misled about the real value of jewels and settings."
NSW Fair Trading received 26 inquiries and 52 complaints about jewellery in 2012.
An inspection of 39 Sydney jewellery stores last year found almost a quarter falsely represented consumer rights regarding refunds.
