I'm out there arguing the Labor case. I will do it anywhere and everywhere that I can. I do it within various communities across Australia where I am able to make a positive contribution. And let me tell you, my voice won't be silenced in the public debate because the issue at stake for Australia are so stark.

If Australia wants an effective United Nations, we have to be comprehensively, not marginally, engaged.

I've been around long enough to not take seriously statements like I am about to be crushed. I'm about how do we seek re-election of the Australian government, how we prevent Tony Abbott from being elected. The bottom line is that it should be all hands to the pump rather than saying other, frankly negative and internally divisive things.

Mr Howard's problem is for so long he's been a climate change sceptic, how can he, therefore, put himself to the country as part of a climate change solution for the future.

We are so fortunate, as Australians, to have among us the oldest continuing cultures in human history. Cultures that link our nation with deepest antiquity. We have Aboriginal rock art in the Kimberley that is as ancient as the great Palaeolithic cave paintings at Altamira and Lascaux in Europe.

A future where all Australians, whatever their origins, are truly equal partners, with equal opportunities and with an equal stake in shaping the next chapter in the history of this great country, Australia.

I do not know whether I will be in this place for a short or a long time. That is for others to decide. But what I do know is that I have no intention of being here for the sake of just being here. Together with my colleagues it is my intention to make a difference .
