I was not laughing at the film, because its silliness is intentional. It is a most dangerous game plot. There are some crazy characters in the film, but also 1 scene where you go WTF, then a reveal has it all nicely make sense.
You may be groaning, but for those wanting a good taste of Ozploitation this is a film to think about.
Turkey Shoot is the nadir of Ozploitation weirdness, for me. It's the product of this decade-long build and pretty shamelessly apes a bunch of earlier ideas of the genre and ramps them to extremes...but it still doesn't make it a good film, to be honest. It's as subtle as a brick to the face and thankfully about half as pleasant, and while there's a lot of fun to be had at the ridiculousness it never really offered anything other than cheap thrills. The camp director is called Thatcher, for christ's sake.
If anyone's interested in a crash course in Australian cinema, I'd recommend checking out David Stratton's new series:
https://www.screenaustralia.gov.au/the-screen-guide/t/david-strattons-stories-of-australian-cinema-2017/34223/ - not sure of it's availability outside of Australia online however. It's fairly fleeting around everything but a few milestones, but it does provide some nice insight and fodder for a list of must-sees from the silents to contemporary cinema.
I'd also really recommend anyone interested in Australian film to check out the works of Raymond Longford - he was a bit of a forgotten pioneer within the silent era, and although a bunch of his stuff has been lost forever, "The Sentimental Bloke" and "On Our Selection" are fantastic works.
https://aso.gov.au/ is a great streaming resource as well, but again I'm not too sure how it goes outside of Australia.
