is it illegal to have sex in a car

Ah, the age-old question of automotive amour. In Australia, the legality of getting frisky in your car depends heavily on location and discretion. Public indecency laws generally frown upon any sexual activity visible to the public, meaning if you're caught, you could be slapped with a fine or worse. However, if you're parked discreetly on private property with no prying eyes, you're likely in the clear. Just remember, flashing your bits where the whole neighbourhood can see might land you in hot water faster than you can say 'handbrake turn.' For the nitty-gritty, check local state laws and council regulations—or better yet, keep it behind closed doors.
