John Howard has gone a bridge too far by not going far enough

As nations we should also commit afresh to righting past wrongs. In Australia we began this recently with the first Australians - the oldest continuing culture in human history. On behalf of the Australian Parliament, this year I offered an apology to indigenous Australians for the wrongs they had suffered in the past.

Politics is about power. It is about the power of the state. It is about the power of the state as applied to individuals, the society in which they live and the economy in which they work. Most critically, our responsibility in this parliament is how that power is used: whether it is used for the benefit of the few or the many.

There are many who criticise the United Nations. And those of us who know this institution well know that it is not immune from criticism. But those who argue against the United Nations advance no credible argument as to what should replace it. Whatever its imperfections, the United Nations represents a necessary democracy of states.

Something my mum taught me years and years and years ago, is life's just too short to carry around a great bucket-load of anger and resentment and bitterness and hatreds and all that sort of stuff.

I deeply believe that if the Australian Labor Party, a party of which I have been a proud member for more than 30 years, is to have the best future for our nation, then it must change fundamentally its culture and to end the power of faceless men. Australia must be governed by the people, not by the factions.

For Australians, climate change is no longer a distant threat. Our rivers are dying, bush fires are more ferocious and more frequent and our natural wonders - the Great Barrier Reef, Kakadu, our rainforests - are now at risk.
