How can I research keywords that are prevalent in Australia if I’m in the US?

I'm familiar with Google Tools (Insight, Trends, SEO Book, etc. etc.). But it seems I can't get enough information on strong keywords in Australia. Big things, like changing "mom" to "mum" make a huge difference in the trends, and a lot aren't big enough to show up. If I do a search from my computer in the US, I'm not getting the same results they would in Australia. What's the best way to be able to get a good geographical representation of keyword phrases for a specific country?
