Welcome to WebmasterWorld!
The site will be in google.com.au, as both use the same index (data). What you may mean is that your site does not show up for searches in pages from Australia...
If that is the case, Google uses some algo to determine where to put a given site. Say, if the web site is hosted in Australia by IP address location. Or if it is registered by someone in Australia according to whois. Or if pages that link to it are from Australia.
So, if your site does not yet show up in "search only pages from Australia" then you may need links from true blue Australian pages.
SEOe you need to own the .com.au version of your website to rank in the pages from australia section..

This simply isn't true. You can rank just fine with a .com.
I don't believe that it is possible for a site to do just fine in .com and not be indexed at all in .com.au - simply because they are the same index with a few different filters applied.
Perhaps consider hosting your site in Australia - but sites that I run generally rank quite similarly in .com and .com.au.
AFAIK, for a web site to be included in Australian searches, it either has to be hosted in Australia or it has to have a .au domain name.
Your best bet is to have a domain with a .com.au TLD. If you can get that, then you know that other search engines will also include your domain in their country-specific Australia. Other things like hosting your web site in Australia can also help with showing up in Google's country-specific search.
Hope that helps,
P.S. Welcome to WebmasterWorld, SEOe.
Be careful not to get your .au tangled up in duplicate filters... ;) We tried hosting a .com.au in Australia purely to rank in Google's page's from Australia, but the domain never made it. In retrospect I wouldn't have uploaded a complete copy of my website to the .com.au, but that's what I did...
Have similar problem my German site version (one domain) is very good listed in google.com for all my important key words but in google.de only about 50% of this key words are up in the SERPS the another words are not existing there. The strange thing is I am listed there for very competitive key words (e.g. "prag hotels" but not for "prag hotel").
Does it mean for some key words is my domain name and web hosting O.K. and for some not?
If its not a .au TLD, then in my experience, you have 2 choices.
1. Get your 'Australian' site listed in DMOZ in an Australian regional category; and/or
2. get the site hosted/ on a nameserver in Australia.
Otherwise - its not an Australian site, is it :)
That's interesting Chris_D. I never knew about the nameserver being a factor. Are you sure about it?
So if I have a .com on US hosting, I can create a nameserver on example.com.au as dns1.example.com.au and I'm in Australia only searches?
What about load balancing with a .co.uk secondary nameserver? I'm not sure, but the more I think about it the more I doubt it. I'd love someone to confirm either way.
No ones 100% sure about anything, are they :)
But I've done enough testing to convince myself.
