Map of Queensland, Australia, showing the locations of acoustic receiver deployments making up the existing (orange) and new (pink) arrays. The inset illustrates four of the five main installation methods i.e. subsurface floats with anchor/weights, star pickets, subsurface floats with anchor/weights with an acoustic release, and surface float setups with anchor/weights. Receivers are also attached directly to underwater infrastructure e.g., wharfs, sensor equipment
