Wyndham Harbour is a combined marina and residential development to be located at Werribee South on Port Phillip Bay. The harbour will have up to 900 wet berths and is to be protected by rubble mound breakwaters. The development will also include new beaches to be constructed to the south and north of the harbour.

A detailed climate change risk assessment has been carried out as part of the design process. The main climate change threats were identified as an increase in mean sea level due to sea level rise, and an increase in the frequency and intensityof storms; with the latter generating corresponding increases in design wind speeds, wave heights and storm surge levels.

As part of the assessment, the main components of the development were considered to belong to four main categories: beaches, breakwaters, harbour infrastructure and foreshore and residential infrastructure. The climate change risks to infrastructure in each of these categories were then assessed independently.

The results of the risk assessment process were then used to develop appropriate adaptation strategies for the main components of the development. As a result, it is considered that the coastal infrastructure associated with Wyndham Harbour has been designed to accomodate the likely effects of climate chnage, at least on a planning horizon to 2100.

This paper will describe the details of the risk assessment process and the development of the different adaptation strategies.
