Mateship is the cornerstone of the Australian way of life until sex enters the picture, that is.

Early results from the bi-annual Great Australian Sex Census reveal four out of 10 people would have sex with a friend's partner if the opportunity arose.

But sex is not everything two-thirds of Australians said they remain with their current partner for love even though their sex life is unsatisfactory.

Australians named tradies, men in uniform and emergency service workers as the hottest-looking workers.'

Almost one in 10 women wants to feature in a porno, 5 per cent of men admitted they fantasise about having sex with a transvestite, and 56 per cent are turned off by fake breasts.

Victorians are the most desperate to have sex with a celebrity and almost half are unsatisfied with their real sex life.

Top of the Victorian sex bucket list is being part of a threesome and partaking in an orgy.

ACT residents prefer the missionary position, South Australians are the nation's most sexually satisfied people and West Australians are most unlikely to forgive cheaters.

Tasmanians admitted they don't know what the "Jackhammer'' or "Spitroast'' positions are and 44 per cent are unsatisfied with their sex life.

The survey probed the sex lives of more than 9000 people, which the Australian Sex Party claims made it one of the largest polls in the nation.

The poll will remain open until February 1 and can be taken by people aged over 18 at www.sexcensus.com.au.
