Portsea Lagoon

Portsea Lagoon is one of the three remaining dunal depressions on the Nepean Peninsula. The lagoon is a natural ephemeral wetland which is due to seasonal variations in both groundwater elevation and weather patterns. Following a dry spell the lagoon fills up with water and after a couple of weeks of inundation the wetland plants grow and the aquatic insects hatch out attracting a wide collection of bird species.

From the viewing platform off Ibis Way in Portsea, the elegant Black Winged Stilts can be seen foraging for aquatic food within the shallows, duck species like the blue Billed Ducks can be observed diving for food in deeper water, Heron species can be seen hunting for amphibians and Eurasian Coot nests made from reeds can be seen floating on top of the deeper water.

You can visit Portsea Lagoon all year round.
