I wrote stories as a kid just for myself. One day, some of the kids in my class found some of my stories in my bag, and I was deeply embarrassed until I realised they enjoyed reading them.
Although my stories are all very different on the surface, I like to write stories about characters struggling with big problems. I'm always reminded, no matter how different from me one of my characters is from me on the surface, how we're all pretty much the same underneath.
At around nine or 10 years of age, young people start to decide for themselves what's moral or not, and that's why I like writing for that age group so much.
Because of my poor writing posture, I started walking in the forest every day, and I found it a potent place to be creatively. It changed me in that it was a new way of doing my creative process, and I realised how much I liked being among tall trees.
Boys, particularly, like stories where they can have images in their imagination, where they can go to scary places and experiment with what can happen.
Halfway through primary school, I realised that I was not as physically strong or fearless as many kids. So, in situations of conflict, I quickly learned that it worked better for me to get out of situations or maybe kind of, you know, prevail in a conflict situation by using humour than by trying to punch somebody out.
I think probably you can either write for kids, or you can't. That ability to imaginatively be a child and see the world as a child and feel and think like a child - you either have that ability or you don't.
I used to get stuck trying to find the first sentence of a story, then I realised that it was often because I didn't know what problem a character was facing in the story. As soon as I did, I could have the character trying to do something about it or have the problem whack him between the eyes.
I was named after my Jewish grandfather who left Poland early in the 20th century. What I knew from an early age was that he had lived most of his life in England, his Jewish wife had died, and he married a non-Jewish woman who was my grandmother.
I've always been interested in setting my stories against a big event, the importance of which my younger readers are slowly becoming aware of as they move into their teens.
In 1969, we emigrated to Australia. It was a big change. The heat, the flies, and the completely different tinned meats. The shock was so great, I stopped reading books for nearly a year.
In all of my books, I'm taking them on an emotionally challenging and sometimes physically dangerous process with a bit of fun and anarchy along the way. With the power comes responsibility.
Kids aren't political, but around 10 years old, they are beginning to develop the moral grounding that might later, in their teens, develop into their first real political perspectives.
Kids who are nine, 10 and 11 are pretty sophisticated readers; they know that there isn't always a good outcome every time and that problems don't always have solutions.
Most of your life after puberty, you're either seeking to reproduce or living with the consequences of having done so. At 70, you start going back to being 11 again.
Step-parenting and being a step-sibling presents a lot of exciting opportunities. When families break up and re-form, there may be less order, less certainty, and a bit more trauma involved, but kids can end up having half-a-dozen parent figures.
The type of stories I write are about young people grappling with the biggest problems in their lives, often problems that are bigger than they're actually capable of solving.
I like to write stories where young people have a strong feeling about something being fair or unfair, right or wrong, cruel or kind, and they act on the basis of that - often in the face of the prevailing limits of behaviour.
