Climate Experience:

Councils have begun a fortification process to protect coastal communities from rising sea levels.


  • Oceans have been absorbing more than 80% of the extra heated added to the climate system, this causes seawater to expand and rise.[1]
  • Melting glaciers and ice sheets also contribute to sea level rise.[2]
  • As sea levels rise they can threaten nearby infrastructure.[3]
  • Victorian waters are increasing in temperature faster than anywhere else in Australia.[4]
  • Southern Australian sea surface temperatures have been above the average for the past 26 consecutive years.[5]
  • Sea level is approximately 225mm higher now than in 1880.[6]


  • Current sea level rise is expected to speed up.[7]
  • If current human activities continue as normal seas would likely rise by over 2m by 2100.[8]
  • 1m sea rise in Victoria will put between 31,000 and 48,000 residential buildings under threat, with a current value between $8-11billion. It will also put up to 3,500km of roads under threat of inundation.[9]
  • 82% of Victorians live within 50km of the coastline.[10]
  • Frequency of storms are also expected to increase, further impacting vulnerable coast lines.[11][12]

What can be done?

  • Email your local MP and tell them that action on climate is important to you and explain the impacts being felt in your area. One email might not feel like much but most politicians consider it to be representative of 100 citizens.
  • Help support the Act on Climate collective by donatingwe are leading the charge for climate action. Your donation helps in advancing policies that prevent climate change from getting worse, we aim to empower communities and build a strong pro-climate-action constituency that governments can’t ignore, and as an added bonus it’s tax-deductable.
  • Get involved with Act on Climate. We meet every Monday at 6pm (upstairs at 312 Smith St, Collingwood) and welcome all newcomers to join in the fight for climate justice. If you are unable to attend, follow us on Facebook, Twitterand Instagram to keep up with the latest campaign.
