I have certainly been very front footed about increasing our gender representation at Westpac.

I'm a very consistent leader, and people won't find me different day to day. You won't have to have the sort of conversation that says, 'How is she today? Is this a good day to have this conversation?' You won't find that situation with me. I treat people with respect.

When I got to be a CEO, I said: 'Right. I'm now going to tackle gender inequality head-on. I'm going to make a difference and lead by example and actively put in place policies and practices to support women.'

42% of our management team are women. So we've reset the goal to 50% by 2017. Because that's when Westpac becomes 200 years old as an institution - the oldest bank, and indeed the oldest company in Australia. So that's a lovely point to reflect on.

Something that I've cared about deeply my whole career is getting to work with filmmakers and inventors of stories that are hysterical because they are just so painfully true.

The work in S, M, L, XL was almost suicidal. It required so much effort that our office almost went bankrupt.

I was a very efficient doctor. I would get rewarded with a lot more patients. By the end of my medical career, I had maybe 2,000 patients in my practice.

The key to understanding my career is that I was never into technology. From the beginning, I brought an outsider's point of view, which is why I write for a layman's publication.
