Here in Australia it's not mandatory but a good idea to belong to a club. In West Australia, where I live, you can't shoot on public land, only on private or at a designated club. You can shoot on your own property, but at least for me, it's not wise as I live in a townhouse. I do occasionally take a few shots in the back yard, thankfully the neighbors haven't said anything, having 6' tall walls surrounding the yard helps! Belonging the club gives me a legal as well as safe place to shoot and meeting other archers makes it worth the time and expense.
