Australian politics is dominated by two misnomers. The Liberal Party is by no means "liberal" and is as staunchly conservative as the Republicans. The Labor Party (yes, they spell it in the American way) haven't been a real part of the labour movement for decades but are really a liberal party. At present the Libs have the government and will probably remain in control for another three years, at least.
Our previous Liberal prime minister, Tony Abbott, would have been welcomed with open arms by the Tea Party and had the political acumen of Donald Trump. It was clear that, after a succession of what one journalist described as "cheerful Tony Abbott demi-blunders", he had to go. Enter Malcolm Turnbull,
Turnbull is as urbane as Abbott was inane. He's a successful and wealthy businessman and a capable politician. He's a leader of our "Ausralian repuublic" movement while Abbott was an embarrassingly sycophantic royalist. I'll vote for Turnbull this year even though, traditionally, I vote for the other party. They are currently in disarray and could not provide an effective government.
The two most capable politicians in Australia at this time are both women. Julie Bishop, our Foreign Minister is tough and experienced, and Penny Wong, Labor's leader in the Senate, is intelligent, capable, and cool under pressure. That being said, I think Turnbull is capable of doing the job on both a domestic and international level.
