I've used a couple of tools for this recently

http://www.rob-millard.com/keyword-expander/

is good

http://suggest.thinkpragmatic.net/

is better.

Anyone know of any similar ones that cover google.com.au?

Adam, did you see that Übersuggest is open source?  It may not be very hard to hack .au results into it.

Übersuggest reporting a HTTP Error 403: Forbidden - not long after the link was dropped here...

Been using this for a while now, presume it has been hammered and the owner got pissed off.

> reporting a http error

still works for me.

fwiw the trends & keyword suggestion tools can be harvested from google

So it is... must be sorted out now then. Nice one.

You guys ever try the wonder wheel?
