Don’t let Sydney Grade Cricket be caught out by climate change

The Sydney Grade Cricket competition is recognised as one of the strongest in the world. It has been among the foundations of Australian cricket since the late 19th century.

But now some of its home grounds are threatened by impacts from sea level rise driven by climate change.

Global warming is warming the oceans. Water expands as it warms. So, the seas are rising: around 200mm last century, and accelerating.

OzCoasts has maps for Sydney impacts of sea level rises of 50cm, 80cm and 110 cm. These maps account for tides, but exclude effects of stronger storm surges – which global warming is likely to bring too.

  • Tunks Park Cammeray, North Sydney’s home for lower grades, would be fully  inundated by the impacts of 1.1 metres sea level rise, and almost completely inundated by the impacts of an 80cm rise.


  • Balmoral Park would only just survive 1.1 metre sea level rise. The nearby beach would get fully covered with water.
  • Birchgrove Park starts to experience serious entry of water from the harbour at 80cm sea level rise. With 1.1 sea level rise the ocean reaches across the ground almost to the pitch.


  • Jubilee Oval in Glebe experiences almost complete inundation with 1.1 metres sea level rise.


  • Tonkin Park, Cronulla shows on Google Earth as having some of its playing area between 2 and 3 metres above current average sea level. It’s right at the edge of the water of Gunnamatta Bay. It isn’t covered by mapping published by OzCoasts yet. Perhaps they could do with a bit more funding with help from the local member, Scott Morrison?

Climate change: the time for games is over
