OK, to be fair, in the New Syllabus, for Stage 5 (years 9 and 10) in "additional content" there are these, which could be what the OP was talking about.
Additional content
Additional content is not prerequisite knowledge for following stages, but may be used to broaden and deepen students' skills, knowledge and understanding in Stage 5. Students:
relate colours of stars to their age, size and distance from the Earth
describe evidence used to support estimates of time in the universe DD
describe some recent contributions made by Australian scientists in the exploration and study of the universe DD
discuss technological developments that have extended the ability of scientists to collect information about, and monitor events in, the natural world CCT
research evidence relating global warming to changes in weather patterns, including El Niño and La Niña CCTSE
examine the factors that drive deep ocean currents, their role in regulating climate and their effects on marine life
research how computer modelling has improved knowledge and predictability of phenomena, eg atmospheric pollution, ocean salinity and climate change ICT
discuss the development and implications of international agreements relating to biodiversity and climate change, eg the original 1987 Montreal Protocol, 1992 United Nations Conference on Environment and Development, 1997 Kyoto Protocol and the 2009 United Nations Climate Change Conference EUSE
outline examples where advances in science and emerging science and technologies significantly affect people's lives, including generating new career opportunities in areas such as astrophysics, geophysics, space science and vulcanology WE
