The thing about social media is that it is anonymous, so it can be much more vitriolic and extreme than normal media and yet it is there for everyone to see. It is kind of like electronic graffiti. The political process is accelerated and intense in a way that I don't believe it ever really has been before.

The one thing that has changed dramatically when you talk to the people of New Zealand and people from Ireland? They feel a darned-sight better about themselves because they made the decision to do what they've done, and I can say to you, we would feel a bloody darned sight better about ourselves once we get an opportunity to put this [vote on same-sex marriage] out there.

It is a very heavy responsibility [to be a prime-minister] to make, but someone has to make it for our country and I am thrilled and honoured to have that opportunity and that responsibility.

I can't promise that I won't continue to embarrass people.

The the relationship between the prime minister and the monarch is very much a personal one and when it comes to the constitution of the Order of Australia, which is headed by the monarch, this is governed by letters patent, which are a matter between the prime minister and the monarch.

I understand that government should live within its means, value the money it holds in trust from you the taxpayer, avoid waste and, above all else, observe the first maxim of good government: namely, do no avoidable harm.

There will be no overall increase in the tax burden whatsoever.
