Former Prime Minister Sir John Key has taken a dig at Australia's political situation.
Speaking at a property conference in Darwin, Sir John said he wasn't surprised to see the latest leadership spill, saying it was part of the "rough and tumble" of politics across the spectrum.
He met five Australian prime ministers across his political career, and he joked: "I used to say, 'mate, I don't really mind who turns up, just wear a name badge so I know who it is'," ABC reports.

Sir John has close ties with former Prime Minister Malcolm Turnbull, who texted him "say it ain't so, bro" after he resigned from politics in 2016.
He said he gave Mr Turnbull a call after the leadership spill that saw him lose his job, saying they're "good friends".
"In the time that he was PM, I thought he did a good job for Australia," he said according to ABC News.
Sir John pointed out he was the 38th Prime Minister of New Zealand and at that time John Howard was the 25th Prime Minister of Australia.
Scott Morrison is now the 30th Prime Minister of Australia.
Despite the tumultuous politics, Sir John said what matters is good public policy, and Australia's had 28 years of unbroken growth "underpinned by a strong natural resource centre".
