Sydney, Feb 18 : A recent survey has revealed that almost one third of Australian youngsters have been unfaithful to their partners at least once.

The online survey conducted by Swinburne University, Victoria University and the Hong Kong Institute of Education found that one in three young Australians agreed on cheating their partners.

The experts believe that this might be due to one-sided relationships.

The collaborated survey led by Susan Moore, a professor of psychology at Swinburne University involved more than 450 people between 18 to 25 years.

"We've found that romantic relationships are very common in this age group, with only 20 per cent never having experienced one,'' News.com.au quoted Moore, as saying.

"Even among that 20 per cent, most are interested but haven't quite got around to it yet,'' she added.

The survey also found that almost 90 per cent of Australians agreed to a break-up and felt hurt or very hurt regardless of who initiated the break-up.

"What we don't know yet is whether the infidelity was the stimulus to breaking up.''

"Another possibility is that it could be due to one-sided relationships, with just under half the sample so far believing that either their partner loved them more or they loved their partner more, as opposed to believing it was an equal love relationship,'' said Moore.

However the researchers suggest that romance and break-ups must be seen as a normal part of growing up.

"Handling romantic relationships or the lack of them - including feelings of loneliness, unrequited love, having your heart broken - is part of the transition to adulthood,'' she said.
