Is sea level falling at Portsea, Victoria, Australia? – thats 60km SSW of Melbourne

The ABC report -Victorian Government ‘not happy’ about extension to Lindsay Fox’s Portsea property – for the uninitiated Mr Fox is a well known trucking magnate.

Perhaps the Mornington Peninsular is rising? I have not heard.
Hoping an informed reader can cast some light.
I like the idea the Victorian Govt is furious with something – shows a sign of life I suppose.
