Hunting and gathering are in my blood. But I've lived long enough to witness a diminution in the seas, and to notice a fragility where once I saw - or assumed - an endless bounty.

I guess it must be a time-of-life thing, looking back and trying to make some sense of who I am and where I've been. It's a weird thing, having to give an account of yourself, to try to make sense of yourself for yourself. I'm not that old, but I have been writing fiction professionally for a long time now. I started so young and went so hard for so long. And I guess it was about feeling I had the space to look over my shoulder.

When I was a girl I had this strong feeling that I didn't belong anywhere,... It was in my head, what I thought and dreamt, what I believed..., that's where I belonged, that was my country.

Past tense offers authority, distance, and present tense offers emotional immediacy.

I grew up in a whaling town. We didn't stop whaling in Australia until 1978. And I've always lived in fishing communities. You could say I'm from the Redneck Wing of marine conservation. Everything I know about the sea I learnt at the end of a spear or a hook. Seems weird to admit it, but I hunted and killed my way to enlightenment. Eventually you see where you've been. All the traces you leave are gaps and absences. And it's a sick feeling, knowing you might bequeath a full dose of Nothing to those who come after you.

Yet however comforting and peaceful beach-combing is, it ends up like the sea, as disturbing as it is reassuring. In dark moments I believe that walking on a beach at low tide is to be looking for death, or at least anticipating it. You will only find the dead, the spilled and the cast-off. Things torn free of their life or their place.

The end of the world begins in the sea we love.
