and their interplay with the intergalactic medium. Specific high-resolution facilities will contribute to answering these questions within a new Centre of Excellence, building on current facilities. Australia is contributing significant investment including
SKA, ESO-VLT, and GMT. Precursor telescopes including ASKAP and the MWA are unique Australian facilities providing key capability to forward ASTRO-HD science. Additionally, space-based astronomy is making an increasingly important contribution to Australian
astronomy, and this will continue with the James Webb Space Telescope.</span><span style="margin: 0px; font-family: Times; font-size: 12pt; color: black"><span style="margin: 0px; font-size: 12pt; line-height: normal; font-family: Calibri, Helvetica, sans-serif;"> </span></span><span style="margin: 0px; font-family: Calibri, Helvetica, sans-serif; font-size: 12pt; color: black; line-height: normal;">The
recent Decadal Plan mid-term review reinforced the priority of these facilities for Australian astronomy during the next decade.</span></p>
