Port Kennedy is built on Becher Point and because of its geomorphological history it is home to an unusual wetland formation, called the Becher Wetland Suite.

The Threatened Ecological Community FCT19, Sedgelands in Holocene Dune Swales, is known to occur in these wetlands.

Port Kennedy is named after a feature in the southeastern corner of Warnbro Sound which was initially named by Surveyor-General John Septimus Roe in 1859 after the Governor of Western Australia (1855–1862), Sir Arthur Edward Kennedy.

[6] Port Kennedy Primary School opened in 1996 and is part of the Department of Education and Training's Peel District.

Initially, with an enrolment of 300 students, the school has grown to about 670 (2009) with a staff of approximately 55.
