A place where you can create art instead of just enjoying it is Parramatta Clay and Arts. If you're not ready to commit to a course, begin with a weekend workshop.
Over three hours, you'll get to create a work of your own, like a teapot, or learn a skill, like Japanese Raku firing. Should that whet your appetite, you can then sign up to a term's worth of weekly lessons.
Another option is to become a member, which gives you independent studio access, the possibility of exhibiting in Hunter Street Gallery of Fine Arts and, once you're an expert, opportunities to teach.
