Since 2009, Portsea Front Beach has experienced severe beach erosion as a result of ongoing swell waves.

DELWP has completed a number of research studies of Portsea front beach and has undertaken short term measures to protect Portsea foreshore with new and upgraded coastal infrastructure.

Most recently, the Department commissioned the Portsea Front Beach Options Analysis report (PDF, 5.1 MB). Advisian (formerly Worley Parsons), an independent engineering consultant, was appointed to complete this study. The report, which was finalised in December 2016, assesses six long term coastal and maritime management options at Portsea Front Beach, and considers local community input and previous wave monitoring data.

The six options assessed in the study are:

  1. Shaping the seabed with dredging
  2. A breakwater seaward of the Portsea Pier
  3. A groyne (s)
  4. Replacing the sandbag wall with a rock wall
  5. Beach restoration or renourishment
  6. Removing and not replacing the sandbag seawall.

As of March 2017, the Department is considering the options assessment for Portsea front beach.
