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.

"We are a mature, independent, confident nation and it's time to stand on our own two feet " Senator Di Natale said.

"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.

I extend my deepest condolences for the families and loved ones of those tragically killed or injured.

Violence and hate have no place in our communities and now more than ever we must stand together against these hateful acts.

Greens Senator for Tasmania, Peter Whish-Wilson, says that last night’s Federal Budget is an admission of failure by the Liberals to deliver for Tasmania's economy.

“First the Government wound up their $6.5 million employment incentive aimed at attracting 2000 jobs; it ending up employing just 160 people.

“The Cadbury’s $15 million grant was a farce from beginning to end. A cent of the money has been yet to be spent despite the Government’s term effectively being over.
