Sundance adopted cycling as his principal means of transport in high school. Since moving to Adelaide in the early 1990s to study at university he has fallen in love with the network of off-road paths through the Adelaide parklands, the River Torrens linear park, and the beachfront esplanade areas, and wants to see such infrastructure expanded and provided in urban and rural communities across the country. He sees mandatory helmet laws and lack of infrastructure as major impediments to a greater uptake of utility cycling.
Sundance holds a PhD in theoretical physics from the University of Adelaide, and is passionate about government policy being based on a rational assessment of high-quality evidence. Beyond cycling issues, he wants to see greater government support for fundamental scientific research, public education, healthcare, and the arts; involvement in high-tech industries (e.g. space exploration, carbon-neutral energy generation, medical biotechnology); protection of the natural environment; protection of online privacy; and the safeguarding of the rights of asylum seekers.
He has worked as a research scientist at Seoul National University in South Korea, the Perimeter Institute for Theoretical Physics in Ontario, Canada, and the University of Adelaide, South Australia. In 2009 – 2010 he travelled across the United States by cycling and camping, from Niagara to San Diego and into Mexico, as well as cycling from Sydney to Adelaide, via Melbourne.
