if you're in Australia ignore all VPN advice. Companies can only come after you for the cost of a single copy of whatever you pirate making it functionally legal here.
Torrents are your best bet for now because they are super easy.
Usenet is a paid service, absolutely worth it but you're paying for at least 2 different services to make it work and setting up a whole bunch of software. Just steer clear of the Arr suite until torrents fail you (and they will)
