I love radio - its immediacy and especially its intimacy... it is part of your life, whispering into your ear. You can't see it, but equally importantly it can't see you.

To the former child migrants, who came to Australia from a home far away, led to believe this land would be a new beginning, when only to find it was not a beginning, but an end, an end of innocence - we apologise and we are sorry. To the mothers who lost the maternal right to love and care for their child - we apologise, and we are sorry.

In economics, one of the most important concepts is 'opportunity cost' - the idea that once you spend your money on something, you can't spend it again on something else.

My commitment to the Republican movement was pure and simply patriotism, a love of Australia... a desire or passion that all of our national symbols should be unequivocally and unambiguously Australian.

I'd love to do radio plays. I think that one should be open to everything and shouldn't limit oneself.

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