Matt, great idea for a website – us Aussies are addicted to pokies, and probably most don’t know about online casinos either.
I’m from more of a sports betting background myself but love to have a slap on the pokies occasionally so can give you my honest feedback too. I think the pokie reviews section would be a promising area to develop, maybe even include it in the header links when you have a few reviews in there. Because I’m sure most Australian pokie players when they come across your site would be looking for Queen of the Nile or some other machines they’re used to playing in the pubs, clubs and casinos. So introducing them to some of the online games and the types of free game features that they have would be a good way to get people to try them out. If you can include screen grab images of what the games look like that would probably help too.
Also it may help to get your site listed in some forum directories to get more members signing up and get some more activity in there. It’s hard to get a forum to take off, but if you can get some good members in there that post regularly hopefully more will join up over time.
Overall I like the look of the site though, and agree with other posts that getting your site visible for some more relevant keywords will help a lot. Best of luck!
