Australian Web Boards - Business Related

[ubergnome]

Any Ozzies out there - Can you recomend a web board such as this one in Australia? I'm looking to reach business people in Sydney and Melbourne.

I've looked at most of the listings from Yahoo and they look low quality.

Same question goes for placing classified ads in Newspapers there.

Any recomendations, time saving tips are much appreciated.

Thanks in advance.
