Christiansen is a Senior Principal Research Officer in the Radiophysics Laboratory working on radio astronomy. His contributions to high resolution studies of the Sun are outstanding. In 1952 he devised an instrument giving high resolution in one dimension, in 1957 another giving resolution in two dimensions and producing actual pictures of the Sun in the "light" of 21 cm radio waves. Christiansen's observations and interpretation have supplied a major part of our knowledge of this aspect of solar radio astronomy. His equipment has since been copied in many laboratories. Prior to joining the Radiophysics Laboratory, he worked on the development of rhombic aerials for long distance communication and the forms he developed are now in use in many countries.

Professor Choo is distinguished for his contributions to human molecular genetics. He was the first to clone the gene for human blood-clotting factor IX, leading to new therapies for haemophilia B. His pioneering work on the human centromere has revolutionised our understanding of chromosome stability and replication. He was the first to describe the epigenetic formation of neurocentromeres in chromosomal fragments, at that time a novel concept that broke the paradigms of eukaryotic chromosome structure and function. His work on the centromere has lead to greater understanding of chromosome non-disjunction, and given impetus to the use of synthetic human mini-chromosomes as vectors for gene therapy.

Samuel Warren Carey is distinguished for his extensive studies of the geology of Australia and Papua New Guinea. He is particularly noted for his contributions to the theory of plate tectonics. He used his analysis of the geology of PNG to build up a detailed picture of indestructible continental blocks mobile over the surface of the globe. Much later discoveries by others of seafloor spreading and subduction replaced his hypothesis of an expanding earth. He played an important role in advancing this major feature of the dynamics of the earth.

Dr Josep Canadell is an eminent world authority and leader in global biogeochemistry, focusing on the impact of human activities on the carbon cycle and global greenhouse gas budgets. He has pioneered work on the dynamics of natural carbon sinks, global carbon stocks, and the biogeophysical processes that drive Earth’s carbon exchanges, producing the most authoritative global greenhouse gas budgets. His research serves as a reference in global biogeochemistry and climate change assessments. Dr Canadell has demonstrated sustained global influence and leadership in translating greenhouse gas information to support climate negotiations and policy development.

Tom Calma is an Aboriginal elder from the Kungarakan tribal group and a member of the Iwaidja tribal group. He was appointed an Officer of the Order of Australia in 2012 and named ACT Australian of the Year in 2013 for his work as a human rights and social justice advocate. Calma has long been a champion for the improvement and advancement of Indigenous peoples’ health, justice, education, and employment status. Calma's research interests include pharmacological application for scabies control, genomics, Indigenous cancers, tobacco control, and micro-biome, as well as health, mental health, and suicide prevention. For many decades, Calma has been a fierce advocate for progress and change, and his work continues to have an enduring impact on public discourse in Australia and beyond.

Tony Burgess developed theoretical procedures to use Simulated force-fields for improving our understanding of protein folding. Subsequently, he achieved the first-ever purification of a protein controlling the growth of white blood cells (granulocyte­macrophage colony stimulating factor, GM-CSF). He was the first to observe that haemopoietic growth factors activate mature blood cells and co-discovered a second haemopoietic growth factor - G-CSF. His group cloned GM-CSF, developing both recombinant mouse and human GM-CSF and the clinical use of GM-CSF in improving blood cell production in cancer patients. His studies on the receptor for GM-CSF have developed a novel explanation for the identical biological effects of different blood cell growth factors.

For three decades Professor Budd has played a dominant role in international research on polar ice. Based on extensive practical experience in Antarctica, he has produced theories and experimental confirmation of the large-scale behaviour of ice which he and his colleagues have used to study the interaction of ice-sheets and climate. His models provide explanations for the initiation and passing of ice ages, and simulate the response of Antarctica to future global warming. His experimental analyses of ice flow provide essential background for the study of ice-core proxy records of past climate. In general, his work unlocks many of the polar region keys to global change.
