NSW 0.74 metres

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 high tide 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. We'll issue maps for that scenario next.

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. 

For each State we will be presenting maps showing impacts on major transport infrastructure, and then move on to show impacts by Federal electorate. If you need a larger version of any image just go to Coastal Risk Australia and type in the location to the search box. Note the disclaimers on the site: these are predictions; reality may well prove worse without rapid climate action.

Our own disclaimers: Images belong to Google and to Coastal Risk Australia. Please advise of any errors in interpretation. (For example, some maps on Coastal Risk Australia's site show blue across elevated railways or roads where local knowledge indicates this refers only to the land or secondary roads underneath; let us know if  in error we have listed any of these as flooded).

Infrastructure

Airports

Sea level rise of 0.74 metres, predicted for this century, would see high tides flooding the northern part of Sydney airport as well as access roads (Marsh Street and Qantas Drive, together with small patches on the M5). 

 Kingsford-Smith_Airport.jpg

Similarly at Port Macquarie, part of the main runway and access roads would be flooded by high tides.

M1_Airport_Port_Macquarie.jpg

Ballina airport would be completely flooded by high tides.

 Ballina_airport.jpg

At Taree airport high tides would come right up to the main runway and flood surrounding roads.

 Taree_airport.jpg

Lake Macquarie airport along with surrounding properties would be almost completely flooded by high tides with 0.74 metres sea level rise.

M5  

As well as minor flooding near Sydney Airport appearing at high tides with 0.74 metres sea level rise, the M5 would be flooded more substantially in at least two locations at high tide: Riverwood 

 M5_Riverwood.jpg

and Hammondville

M5_Hammondville.jpg

M2

With 0.74 metres sea level rise the M2 and Epping Road are partially flooded at high tides at the Lane Cove River crossing.

 Princes_Boydtown1.jpg  Princes_Boydtown2.jpg
   

Rail

0.74 metres sea level rise would bring flooding at high tide to several locations on the NSW rail network.

Sydney area

On the Sydney Trains network these include Riverwood on the Macarthur - Airport line:

On the NSW Central Coast, flooding shows on Coastal Risk Australia's maps for 0.74 metres sea level rise at Wondabyne on the line from Sydney to Gosford, Newcastle and north to Brisbane:

Railway_Wondabyne.jpg

Boolaroo, also on the line from Sydney to Newcastle and north:

Railway_Boolaroo.jpg

Sandgate to Hexham and almost to Tarro - cutting the north coast and north west lines including interstate freight and Hunter passenger and freight services:

North coast

Further from Sydney, 0.74 metres sea level rise would bring high tide flooding to several more points on the north coast line to Brisbane including Rossglen:

Ports

The Coastal Risk Australia maps indicate that access routes to the ports of Sydney and Wollongong just miss being affected by flooding at high tides with 0.74 metres sea level rise. At the Port of Newcastle however, it would be a different story. As well as major regional rail and road routes leading to export facilities at Newcastle being affected by flooding (as shown earlier on this page), rail and road facilities within the Port of Newcastle itself would be flooded.
