Organisations recommendations for western/Southwest Sydney

Hey all. I'm based in Campbelltown and looking to get involved In a socialist organisation. If anyone has any suggestions or advice on organisations locally I'd love that. I've been looking into potentially joining RAHU but they seem based mostly in Melbourne. And "Riseing Tide" seams to be doing some good work on fighting for serious action on climate change.

Also a side question on the issue of housing. Does a general housing strike, Renters and mortgage payers refusing to pay seem like something that would be effective in pushing for the decomodification of housing? I'm currently paying a mortgage but I would rather a society where everyone had free or affordable, secure housing. Even if that meant I technically didn't own my home (not that I own it now, the bank owns 80%).
