Newcastle has been featured as a high risk zone on a new map by Coastal Risk Australia, showing sea level rise patterns over the next 100 years.
The interactive map also shows that along with Carrington, Wickham, Koorangang, Fletcher, Shortland and Hexham are among the worst effected by rising sea levels.
Greens MP Justin Field says, the new data must be taken seriously by the NSW Government.
The rising sea levels are set to completely change the landscape of coastal communities, and in places like Carrington there's billions of dollars of public and private infrastructure at risk.
Not only that, MP Justin Field says the housing market will also be affected as the weather patterns change.
"This is already happening, we saw last year major storm events impact the coastline and saw houses washed into the ocean. I know that property prices are still high along the coastline but I think insurance companies are starting to look at this data and ask whether or not these properties are insurable and when you see those questions asked you'll see those prices start to fall," said Justin Field.
