It’s located within the Entertainment Quarters which you can go in - there’s a cinema, a few bars and restaurants there but Fox Studios itself is closed to public. There’s security at the entrance to get into the sound stages and studio lots and you won’t be able to go past them. The section that used to be that short-lived theme park is still there with all its fancy buildings but it’s been taken over by production companies using it as offices. If you walk up to Heritage Park near the film school you can see the studios but it’s fenced off. Entertainment Quarters is worth visiting anyway. There’s a small market on Saturdays and Mi Piace make good pizza!
