We are already experiencing the symptoms of climate change, especially with a hotter and drier climate in southern Australia - the rush to construct desalination plants is an expensive testament to that.

Newspapers are busily experimenting with different models. Traditionally, and I suspect in hindsight very mistakenly, online news was free. And once given free access readers felt it was their entitlement.

On balance, after weighing the arguments, I believe that the time has come for Australia to create a new sovereign wealth fund.

The proliferation of outlets that digital technology has enabled has itself contributed to the changing nature of what we regard as 'news' and the way in which many citizens perceive politics.

Look at countries like China, they are determined to dominate all clean technology areas, putting lots of money into wind, solar, electric vehicles and battery storage. America's political impotence, caused by their terrible partisanship, will see them left behind.

Let us be honest with each other. The threat to marriage is not the gays. It is a lack of loving commitment - whether it is found in the form of neglect, indifference, cruelty or adultery, to name just a few manifestations of the loveless desert in which too many marriages come to grief.

I do not believe we can effectively move Australia to a lower emission economy, which is what we need to do if we're going to make a contribution to a global reduction in greenhouse gases, without putting a price on carbon.

It is our job, as members of parliament, to legislate with an eye to the long term future, to look over the horizon beyond the next election and ensure that as far as we can what we do today will make Australia a better place, a safer place, for future generations to live in.

I will go to the next election saying to Australians, vote for me, vote for the Liberal Party, and I will become your PM. So I'm offering myself as the alternative PM - that's one way people describe the Leader of the Opposition - but I'm not in politics for myself to realize a personal ambition.
