How many white guys in the Liberal Government?

I found this really great video by The Ministry of Truth satirising the Liberal government's recent anti-union advertisements.

It really questions how representative democracy can work in "multicultural Australia" when the government is predominately rich, white and male. Why do we continue participating in elections and living within this system when those who make the decisions aren't even representative of a large amount of people?

I'm sure the Labor party isn't that much better. However, their affirmative action policy would mean they have at least more women than Liberal.
