The Transect from the Gawler Craton through the Office Basin, the Musgrave Block and into the Amadeus Basin (Gawler-Officer-Musgrave-Amadeus-GOMA) was a collaboration between Geoscience Australia, PIRSA and AuScope.

AuScope contributed 200 kilometres of the 580 kilometre profile and in particular supported the part of the line that bridged the South Australia/Northern Territory border.

AuScope supported 180 kilometre line of the transect, of a total length of 197 kilometres. Data was processed by June 2010 and the first interpretation workshop held in Melbourne. MT data was acquired along the transect.

The interpretation of the Southern Delamerian survey was completed and results were launched in March 2011.

A cooperative venture was established with the Geological Survey of Western Australia for 580 kilometres of reflection traverse from the Pilbara Craton to the northern YilgarnCraton with a funding split of 50:50.

AuScope contributed $1.5 million to the 580 kilometre group of reflection profiles. The transect was completed in May 2010 with good quality data. Processing of the Capricorn data was completed and interpretation workshops were held in Perth in April and June 2011.

In late 2013 a major transect was started across the Nullabor plain linking reflection work in the Albany -Fraser complex,undertaken by GSWA,to the GOMA profile.

The 834 km long profile followed the Trans Australian Railway and was supported by GSWA, GSSA, GA and AuScope. The data quality was very good despite the presence of complex structure near surface. The eastern part of the profile was released in late 2015 with an interpretation workshop in Adelaide in December 2015.
