Outputs from the Program - Onshore The onshore program continues to be delivered through integrated projects of data gathering and assessment, conducted at national and regional scale. In most jurisdictions, the program has leveraged supplementary funding from state and territory geological surveys. Funding through AuScope Ltd made it possible to extend deep seismic survey lines in some regions. The arrangements and collaborative engagement with state and territory officials was formalised in schedules under the NGA.
