Right on bro, Australia is smaller so they look at whats happening in the states and the UK and basically copy and paste the law with a few extra things they can get away with
p.s you can drink alcohol in the houses, but I get your point, you cant legally smoke in your house, and if you ayahuasca you will probably get shot

I'm pretty sure you also cant legally walk on the right side of the road? might need to check me on that one
