Movie is about rich girl (rich family) and some guy. She pays that guy to play her boyfriend. The real boyfriend of that girl is cheating on her (there is a scene where he haves sex with some girl in pool-aquarium and all is seen by guests in local bar through bar window-aquarium, even fake boyfriend sees that, after that he gets a black eye by the real boyfriend)
In the end of the movie the fake boyfriend is flying away and the rich girl begs her father to help her somehow, he gets a phone... And the plane comes back and lands, he says something like "i'm very rich man"
I think its an a Australian movie but not 100% sure
