It’s the excitement of being on the frontier.
I think what drives scientists is this tremendous intellectual adventure – pushing the boundaries of knowledge, walking down a track that nobody has walked down before, not knowing what's around the corner and then seeing a landscape that is so extraordinarily beautiful and complex, being part of the community that is driving the boundaries of knowledge and giving us insight into the amazing process of life.
It was one of those special places of science where people were really passionate about their work and they were asking big questions and competing with the best in the world.
It's the colours, the light, the space. It's really very deep in my soul… In the Australian bush and inland deserts, there is a sense of being the first person in a place.
