Factual error: If you've ever been to Sydney you'll realise howw wrong a lot of the locations are in this film. For example the girls are apparently "surfing" at Manly Beach, a huge surf beach almost three kilometres long on the Northside of Sydney. The girls actually "surf" at a waveless, inner-harbour bay about one hundred metres long that I believe is in the Eastern suburbs. You can actually see land beyond the water.
Factual error: When the dad comes out you see a dog. The dog looks fake because dogs don't bark while snarling.
