G'day Josh, Welcome and enjoy.

check out the sited pinball thread to check out pinballs in your local area even in Newcastle at Pinball and Pizza (after 4pm) always have 6-7 out the front as well as there are quite a few pins spread out in Newy and Central Coast by Luke. I have put a (L) behind his pins as they are all really nice playing pins and often he is open to selling select ones.

but like what ajiard said, better if you can play first. If in doubt start a thread and ask for help.
