Old fart Aussie software dev here, as recently as the early 90's Australia (and the US/UK) considered encryption techniques to be a "munition" for export purposes, it was illegal to export anything stronger than 48bit. Then
some bloke put out some OSS called PGP (Pretty Good Privacy), he had stayed within the regulations by using something like #define BITLEN 48, but also given the world an algorithm that could be trivially changed to any arbitrary length and re-compiled. This created a legal paradox that drove the customs people nuts, there was a huge fuss about it at the time but eventually the various governments realised the regulations were unenforceable and dropped/ignored them.
Aussies made a huge mistake at the last election. This mob have managed to politically unite Aussies (against them) in a way I haven't witnessed since the downfall of Gough Whitlam (IMO - due to GW's "sore loser" re-election campaign). Trust us, we have mandatory voting and will boot this embarrassing mob out the first chance we get. There isn't a sector of Aussie society they haven't upset in the past year alone, the only chance the conservatives have of winning is if they put Turnbull back in charge and allow him to purge the "tea party" types from the current cabinet, they have way to much power for the tiny slice of Aussie society that they represent.
