Australian travellers should be wary of scams, tricksters and cons when venturing overseas this summer.

Cheap Flights travel expert Ben Rosier warns scammers will often abuse the kind and trusting nature of Australian travellers.

“In a foreign country people let their guard down, relax, and often behave in a way they never would back home - leaving them open to highly-organised tourist scams,” Mr Rosier said.

SureSave executive director Michael McAuliffe said travellers may not realise they’ve been had until it is too late and often are too embarrassed to report the incident.

“All it takes is a momentary lapse of judgement to fall prey to scammers, and yet you might regret it for a very long time,” Mr McAullife said.

Australians are told to learn from past travellers’ mistakes and, if in doubt, call the police.

Common cons include counterfeit cops, un-genuine gems, taxi troubles, devious distractions and bar bilks.
