Australian Greens Leader Richard Di Natale has laughed at Prime Minister Malcolm Turnbull's assertion that that a re-elected Coalition would deliver stable government.

"Malcolm Turnbull rolled a first-term prime minister, presides over a divided party room with Tony Abbott waiting in the wings, and called a double dissolution in a desperate bid to earn a mandate from his own party," Senator Di Natale said.

The Australian Greens have formally launched their 2016 campaign with the entire federal Greens party room, former party leaders Bob Brown and Christine Milne, and hundreds of supporters in Melbourne.

"Our 2016 federal election campaign is focused on protecting the climate that sustains our health, our environment and our economy, tackling inequality and charting a better way to deal with today's record levels of global displacement.

Greens Leader Richard Di Natale is marking the Queen's Birthday by setting out a 5-step path to allowing Australians to serve as our own heads of state.

"It's on days like today that many Australians remember the failed republic referendum of 1999. The Greens have a clear plan to ensure history doesn't repeat itself.

I am devastated to hear of the horrific news of another violent and senseless shooting in the United States.

Our hearts are with the people of Florida and the LGBTI community.
