Abstract
Fresh groundwater stored in Australian coastal aquifers is an important resource for humans and the natural environment. Many Australian coastal aquifers are vulnerable to seawater intrusion (SWI)—the landward encroachment of sea water into coastal aquifers—which can significantly degrade water quality and reduce freshwater availability. The increasing demands for fresh water in coastal areas and the anticipated impacts of climate change (such as sea-level rise and variations in rainfall recharge) may result in increases in the incidence and severity of SWI. Comprehensive investigations of SWI are relatively uncommon and the extent of monitoring and investigations specific to SWI are highly variable across the nation. In response to the threat posed by SWI, Geoscience Australia and the National Centre for Groundwater Research and Training, in collaboration with state and territory water agencies, undertook a national-scale assessment of the vulnerability of coastal aquifers to SWI. This assessment identified the coastal groundwater resources that are most vulnerable to SWI, including future consequences of over-extraction, sea-level rise, and recharge–discharge variations associated with climate change. The study focused on assessing the vulnerability of coastal aquifers to the landward migration of the freshwater–saltwater interface, rather than surface waterbodies.

Purpose
This report was compiled and written to summarise the four-year (2008 to 2012) project assessing national vulnerability of groundwater in coastal aquifers to seawater intrusion. This project was funded by the National Water Commission (NWC) and was undertaken by Geoscience Australia in collaboration with the National Centre for Groundwater Research and Training, with support from Australian, state and territory governments. The original Waterlines report was published in pdf format on the website of the National Water Commission.

Lineage
This summary report presents the key findings and outcomes of the four-year national seawater intrusion project. The work was a desk-top assessment compiling results from previous investigations, and applying new analysis and interpretation.
