You know, I'd hold off on Ansell until you've got a few more dives under your belt.
It is one of my favourite sites, but it is an advanced site. The wall doesn't have much in the way of ledges, so it is essentially a 'bottomless' site.
The hike to & from the entry point is pretty infamous. It depends on what kind of shape you're in AND how used to hauling dive gear around AND whether you have gear that is somewhat comfortable on the surface. But it has quite a few stairs and then a fair walk down a trail. It is being cleaned up quite a bit, but it's still a little treacherous. As are the rocks at low tide.
Rereading my post, I realize it sounds pretty negative, but like I said, I really like Ansell. I've had some excellent dives there and some really cool wildlife encounters, but I think for now you'd probably get more out of doing another site with less, um, "character". Have you done Porteau yet? There's also the VT100, which is a short walk, but a little treacherous in its own right... however it has a nice slopping bottom.
Wherever you go, i hope you have a nice dive.
