Surprises are often a pleasant part of travel but an unpleasant and costly one may await on the return home.
Consumers seem to be losing out when it comes to spending overseas even when travelling on a buoyant home currency, a study finds.
Some 36 per cent of Australians seriously overspend on holiday and 21 per cent run out of funds mid-trip, the survey by online finance comparison service Mozo finds.
And 24 per cent of those surveyed take more than six months to pay off a holiday credit card debt.
Mozo managing director Rohan Gamble said travellers often don't consider the extra charges they might incur overseas.
