Rated #10 on Luke Buckmaster's list of Ozploitation films. Essentially a James Bond clone crossbred with Kung Fu (it was peak Kung Fu in 1975), hang gliding and a bit of everything else. Director Brian Trenchard-Smith is proud of his work (mostly stunt-focused schlock, most famously BMX Bandits) and instructs us to switch our brains off and enjoy. The initial scenes at Uluru, while clunky, promise more than the rest delivers, if only because they are unfilmable now. Those in Hong Kong and Sydney are far more generic.
Luke Buckmaster at length in 2016. Jimmy Wang Yu was eclipsed by Bruce Lee, and George Lazenby quit the Bond racket perhaps sooner than he should have. Overall more fun to read about than to watch.
