News New seabed maps show Bass Strait in unprecedented detail

Published:14 February 2023

The Australian Government has released a new seabed map of the Bass Strait that shows the area in greater detail than ever before.

The new map – produced to a 30-metre resolution by Geoscience Australia – reveals key underwater features including submarine canyons, ancient land surfaces and the location of the former Bass Lake.

The map is a result of ongoing work between Geoscience Australia, James Cook University, the Australian Hydrographic Office and Deakin University.

Geoscience Australia’s work involves mapping and characterising Australia’s seabed using its own data, along with data provided from its partners, to produce high-quality maps that are valuable across multiple sectors.

Geoscience Australia brings these seabed maps together with other spatial information to inform decisions about the sustainable use of Australia’s marine jurisdiction.
