Free/Cheap Classes (like at a community college) (Sydney)

Hi,

I only moved to Sydney recently after completing a Bachelor's degree in the US, and I still don't have a job unfortunately (but perhaps that's a story for another thread)?

Basically, I'm looking for free or cheap classes (art, music, cooking, acting, dancing, languages - anything really!) like those offered at a community or junior college in the US - that is, if they have anything like it in Sydney. Ideally, I'd love someplace in or near the city or the Eastern suburbs, as I don't have a car :)

Thanks so much in advance to everyone who responds!

All the best,
ZC
