See: Australia in box seat to become world's new rare earths powerhouse. Dr Foley notes that post-covid Australia needs to become more sustainable in several industries. She also states that STEM (science, technology, engineering, and maths) is essential in ensuring Australia does not become too dependent on other countries. However, Dr Foley also notes that Australia must continue to collaborate internationally. Dr Foley has been a champion of diversity in science and leadership, and she is keen to attract more girls and women into STEM subjects. Think about the significance of Dr Foley's expertise and possible implications for future defence technology development.
