Cover page artwork:Seven Sisters, 2024Noeleen Hamlett, Wajarri Yamaji “The Seven Sisters in our night sky guiding us in our search with the telescopesandChristmas tree-shaped antennas. Leading us into a better future, as we cometogetherat our meeting places, taking a big step forward.”” This artwork is part of the Cosmic Echoes: A Shared Sky Indigenous Art Exhibition, which isanSKAO initiative, in collaboration with South African Radio Astronomy Observatory, CSIROandthe Wajarri Yamaji Aboriginal Corporation. The Wajarri Yamaji are the Traditional Ownersand Native Title Holders of Inyarrimanha Ilgari Bundara, the CSIRO Murchison RadioastronomyObservatory, where the SKA-Low telescope is being built. Noeleen’s artwork includesrepresentations of antennas from the SKAO’s SKA-Low telescope as well as a dish-shapedantenna of CSIRO’s ASKAP radio telescope in the foreground. Noeleen Hamlett bio: I grew up in the small town of Mullewa on Wajarri Country in Western Australia. As a childIwas inspired by my mum and brother who carved emu eggs. I have 8 daughters and15grandchildren and currently live in Perth where I studied Visual Arts. As a professionalAboriginal artist, my art and research practice often combine traditional practice withunconventional techniques using other mediums that transform the image to a narrativeof‘Memory and Land’. This combination explores how conflicting mediums work together,creating a unique visual language and representing historical stories as part of an ongoingproject. A key intention is to invite the viewer to a closer understanding of Wajarri’s uniqueculture through exploring land from topographical views of location. I will always haveapassion for my culture and Country. ACKNOWLEDGEMENTOF COUNTRY The Australian Academy of Science acknowledges and pays respects tothe Traditional Owners of all the lands on which the Academy operates,and where its Fellows and employees live and work. The Academyrecognises Australia’s Aboriginal and Torres Strait Islander peoples as thefirst innovators and scientists of this land and honour their enduringconnection to Country, from which we are committed to learn. We payour respects to, and recognise the cultural authority of, their Elders pastand present. EDITORIAL NOTE This decadal plan is the culmination of over two year’s effort by the Australian astronomical community.The plan is based on the reports of 13 working groups, comprising more than 250 astronomers, and an extensivesurvey of more than 550 members of the astronomy community including staff and students from more than30 Australian institutions across all states and the ACT. The working group reports are published electronically aspart of the Decadal plan at the following address:here. The Decadal Plan was edited for the National Committeefor Astronomy by an editorial board that included Professor Virginia Kilborn (Chair), Professor Sarah Brough(Deputy Chair), Professor Tamara Davis AM FAA, Professor Michael Ireland, Professor Chris Power, andProfessor Cathryn Trott. We gratefully acknowledge the financial support provided by CSIRO, Australia’s national science agency, andfunding from a bequest by the late Professor Michael Dopita AM FAA to the Australian Academy of Science, whichsupported the development of this Astronomy Decadal Plan. AUSTRALIAN ACADEMY OF SCIENCE’S NATIONAL COMMITTEE FOR ASTRONOMY Thank you to the Chair and members of the Astronomy Decadal Plan editorial board, who have worked tirelesslyto bring this report to publication. Thanks also extend to members of the Working Groups, who have allcontributed significantly to its development, and to the members of the astronomy community who contributed,whether that be by hosting or attending a consultation workshop, providing input or by contributing photos tohelp this plan truly reflect the breadth of Australian astronomy.
