I can't think of anything filmed in Ipswich where I live. Quite a few things get filmed on the Gold Coast (from memory Scooby Doo, Triangle..), which is sort of nearby, but that's about it.
Oh, I tell a lie, I just saw Daybreakers the other night and that's filmed in Brisbane. It's not set in Brisbane and is full of Americans (and Australian actors doing dodgy American accents), which is kind of weird when you know the place and can recognise the landmarks.
i live in a suburb of only 2220 people, & I was walking to a friends house 1 night, to take her something, & there was a film crew in her street! The food cart was on her lawn, & various garages had been rented out for around the $200 mark. The movie was, The Square. We happen to see the movie at another friends house, a few years later. I think the 2 brothers who are actors, actually directed this film. (You'll have to look up the details of The Square, if you want to know anything else about it!)
