A southern Victorian Shire is considering rising sea levels in its next planning amendments.

Councillors from the Bass Coast Shire have reportedly discussed changes at a meeting overnight, which take into consideration the most recent storm surge and tide data, and would make developing coastal and riverine areas considerably more difficult.

The Council heard figures that say large areas of the municipality will be flooded by storm surges, wind, wave and tides over the next 80 years, combined with potential sea-level rises of over a metre.

With Council planning laws often held responsible by angry residents after flooding, the move can be seen as an application of forethought based on relevant data to protect residents, property and the Council itself.

An official announcement on the proposed changes to the Land Subject Inundation Overlay is expected soon.
