Set in Queensland Australia
Charlie only says one Word throughout the whole film: "Pretty".
Natasha mentions that Jason owns a "Halloween Hockey mask". He corrects her by telling her that it is a limited edition Friday the 13th Jason Voorhees mask. Kane Hodder, who plays Tony Stewart in the film, has portrayed Jason Voorhees in the past.
This is also an allusion to the Halloween movies, which started the slasher movie craze of the 80's.
Jason Voorhees is a rip off of Michael Myers, the antagonist of Halloween, which is why Natasha mixes them up.
