In fact, soon after that [South African sanctions], I was going on an official visit to the UK and Margaret Thatcher instructed every minister to clear the decks of any outstanding matters between us - Australia and the Brits. And she went out of her way to make sure that that was as successful a visit as it possibly could be.

It was very much an Australian/New Zealand initiative to have a nuclear free South Pacific. And the Americans were very apprehensive about this. So, I explained to them that, as far as I was concerned, this didn't involve any diminution in our commitment to the ANZUS relationship. But David Lange took it further and he barred visits of US nuclear warships to New Zealand.

There is a reciprocal respect for [ Elizabeth II], for her interest in the Commonwealth. The members of the Commonwealth recognise that here is a genuine interest from the top. So, that's one reason. I'm not putting it necessarily in order of importance.

Peoples have come to experience that political structures and divisions of power are not immutable. Nor will they perceive the distribution of wealth and resources between nations to be unalterably ordained by heaven and incapable of drastic rearrangement by the less than gentle manipulation of man.

The essence of power is the knowledge that what you do is going to have an effect not just an immediate but perhaps a lifelong effect on the happiness and wellbeing of millions of people and so I think the essence of power is to be conscious of what it can mean for others.

One of the features of the Commonwealth Heads of Government Meetings was [that] she [ Elizabeth II] would have a meeting with each of them. You'd have an allotted time.

We [ with Brian Mulroney and Rajiv Gandhi] went to the meeting in Canada [the 1987 Vancouver CHOGM] and I said to them there that sanctions weren't working; they were just being busted. And it did seem to me that one way that we could bring the apartheid regime down would be if we did mount an effective investment sanction.
