West Australians looking for love lost almost $25,000 a day to romance frauds last year, with losses rising a staggering 900 per cent from 2012.
The latest figures from Consumer Protection reveal 187 victims were scammed out of $8.97 million last year.
Equal numbers of male and female victims lost an average of $48,000 to the scams.
The figures represent a dramatic rise in WA victims, with just 23 people reporting a total loss of $870,000 in 2012.
Commissioner for Consumer Protection Anne Driscoll said it was important people having an online relationship were wary of fraudsters.
"The photos are fake and the identities usually stolen from the internet, particularly from Facebook profiles," she said.
"While the relationship is created in the virtual world, there are physical gestures which, for the victim, make it seem real."
Fraudsters were professional in their deceit, sending flowers, cards, photos and in one case a perfumed handkerchief to appear authentic.
"One victim received a sketched drawing of her and the man from their photos posing as a happy couple - all tricks designed to distract the victims from doubting the true motivation behind the requests for money that ultimately come," she said.
Linda, not her real name, lost hundreds of thousands of dollars in one month after a man claiming to be a US miner who had moved to Perth contacted her via a dating website.
He encouraged her to take down her dating profile because they were meant for each other and Linda, 55, was asked to send money so he could finish a construction job overseas.
Linda said she was suspicious initially but it was only after contacting a friend in the financial industry that she realised she had been scammed.
"If you're involved in it you possibly can't see it, whereas someone who is not involved can," she said.
"If you're confused, ring ScamNet. They can probably quickly check some information and verify if this person is real or not."
The Project Sunbird team recently contacted six women, three from WA and three interstate, to tell them they were all dealing with the same man.
They had sent him about $550,000 in total over six months after being asked to help pay for equipment needed for a building project.
Det-Sen. Sgt Dom Blackshaw, from the major fraud squad, said investigators were sadly getting a better picture of the true extent of romance fraud as they continued to alert and engage victims, particularly through their letter program.
