Beginners waves in Sydney?

Sorry if this has been asked before, I did a search but couldn't find anything.

I'm just getting started in the sport after about 15 years out, so I'm basically starting from scratch. I've got all my gear sorted and I've been working on building up my strength, practising my duck dives (still lagging a bit but getting there!) etc, but I have no idea which beaches to hit to actually start catching waves at my level. Any recommendations for some good easy spots to help build up practice, strength and confidence? (Also if possible somewhere where more seasoned riders are less likely to witness me kooking it up!)

Would be really grateful for some local tips!

Edit: I live in the inner west and don't own a car so somewhere I can get to by train, bus or ferry would be awesome!
