Maps on this page have been generated from Coastal Risk Australia's site which uses Google Earth Engine and the Intergovernmental Panel on Climate Change Fifth Assessment Report scenarios for sea level rise this century.

Maps show inundation levels at the highest tides based on a 0.74 metre sea level rise.

In the Fifth IPCC Assessment Report (2013/14) this was regarded as a high end scenario for 2100. More recent studies indicate that this level may be reached substantially before 2100, and that 2100 sea level rise may reach more like 2 metres, with far worse impacts accordingly. The Coastal Risk Australia website also allows you to model up to 2 metres sea level rise. 

Maps on this page are grouped by Federal electorate.

These maps make (very painfully) clear some of what Australia has to lose from sea level rise, and how important it is both to take serious action to minimise the amount of human-caused climate change, and to take seriously the need to adapt to the climate change we are unable to avoid. 

If you need a larger version of any image just go to Coastal Risk Australia and type the location in the search box.

Note the disclaimers on the site: these are predictions; reality may very well prove even worse without rapid climate action in Australia and internationally.

Our own disclaimers: Images belong to Google and to Coastal Risk Australia. Please do advise of any possible errors, including where the maps need some interpretation. (For example, some maps on Coastal Risk Australia's site might appear to show blue across elevated railways or roads, but local knowledge and a close look at the maps fairly clearly indicates this refers only to the land underneath; let us know if in error we may have included any infrastructure in this category as flooded).

Barker | Hindmarsh | Mayo | Port Adelaide


0.74 metres sea level rise would mean some flooding at high tides in Rosetown;


in Beachport;


in Robe


and for several kilometres of the Southern Ports Highway east of Robe:



0.74 metres sea level rise would mean flooding by high tides for most of West Lakes including Football Park:


as well as widespread flooding in Grange


including this closer view of the railway and surrounding properties


There would also be flooding at high tides at Henley Beach


and at Glenelg North


At Adelaide Airport 0.74 metres sea level rise would be only just below the level  at which high tides would bring flooding onto the runway:



0.74 metres of sea level rise would mean flooding at high tides for some streets and properties in Goolwa:  


Port Adelaide

0.74 metres sea level rise would mean flooding at high tides for some parts of Outer Harbour including road and rail links to the port: 


Road and rail links to the port would also experience flooding together with local streets and homes at Osborne:


and at Taperoo and Draper:


There would also be flooding at high tides for homes at Largs, Peterhead and Birkenhead together with some further flooding of port road and rail access:


There would be widespread flooding of streets, homes and parks and reserves in Semaphore as well as the railway line between Glanville and Ethelton stations:


0.74 metres of sea level rise would mean widespread flooding at high tides for homes and other premises and for local streets and major roads in Port Adelaide 


in Rosewater


in Ottoway


and in Wingfield


There would also bee flooding at high tides for streets and properties in Globe Derby Park including for the harness racing park itself:
