Aurgh. I could start to describe them, but the time zones are all screwed up at the moment.
Late Night Raw - Friday - 9.30pm
Smackdown- Saturday - 7.30pm
Apart from the others, look for yourself. There's an online guide (don't know how good or bad it is though)
EDIT: That's for Foxtel. I have no idea about Optus so if they're different, meh.
