Caring for Country in Arnhem Land
Macquarie University Eureka Prize winners

Macquarie University congratulates its winners in the 2017 Australian Museum Eureka Prizes and the winner of the Macquarie University Eureka Prize for Outstanding Early Career Researcher.

High-power diamond lasers invented at Macquarie University

High-power lasers have many potential applications: from medical imaging to manufacturing, shooting down drones or space junk, or powering deep space probes. But current laser technologies overheat at high power.

Rich Mildren and his team have developed a technique to make diamond lasers that, in theory, have extraordinary power range. Five years ago, their lasers were just a few watts in power. Now they’ve reached 400 watts, close to the limit for comparable conventional lasers.

Rich Mildren won the Defence Science and Technology Eureka Prize for Outstanding Science in Safeguarding Australia.

A unique collaboration between scientists and Aboriginal people in remote south-eastern Arnhem Land is building knowledge about country and how local people can better manage it.

In the last nine years the Ngukurr Wi Stadi bla Kantri (We Study the Country) Research Team has discovered species new to science, found new populations of threatened species, preserved culturally-significant wetlands, and documented the community’s plants and animals in eight local languages.

Led by ecologist Dr Emilie Ens from Macquarie University and Ngandi Elder Cherry Wulumirr Daniels, this citizen science research is also working with the Yugul Mangi Rangers to better manage the new threats facing their country—like feral animals, weeds, climate change and altered fire regimes.

The project is blending ecological methods with traditional knowledge and ways of seeing country. “Our ancestors were rangers. We were rangers for 40,000 years and are rangers today,” Cherry says. “It’s a responsibility for us to look after those things.”

“We are not doing it for ourselves. We are doing this for our country and for our people and for the sake of our culture, keeping our culture alive and strong.”
