i usually buy JAV for my meta quest vr, but these sites have non-VR stuff too

first one is afesta.tv, they have a couple of studios there but the one where I buy most stuff from is dmm.co.jp
however there are a few caveats because you probably live in Australia, first being you need to use a VPN and connect to a Japanese server. Second being you need a PayPal account and purchase "DMM Points" because you can't use foreign credit cards on the site.
But once you've purchased some stuff, you don't need a VPN to view your purchases.
