69. Flinders - Coastal Bluff and Cliff

This information has been developed from one or more of these publications:

  • Sites of Geological and Geomorphological Significance in the Westernport Bay Catchment (1984) by Neville Rosengren.
  • Sites of Geological and Geomorphological Significance in the Western Region of Melbourne (1986) by Neville Rosengren
  • Sites of Geological and Geomorphological Significance on the Coast of Port Phillip Bay (1988) by Neville Rosengren.
  • Sites of Environmental Significance in the Flood Plain of the Upper Yarra Valley Region (1983) by Neville Rosengren, Douglas Frood and Kim Lowe (as part of a study of Sites of Environmental Significance by the University of Melbourne for the then Upper Yarra Valley and Dandenong Ranges Authority).
Geological heritage sites, including sites of geomorphological interest and volcanic heritage sites, are under regular revision by the Geological Society of Australia, especially in the assessment of significance and values. Reference should be made to the most recent reports. See the Earth Science Heritage section of the Geological Society of Australia website (external link) for details of geological heritage reports, and a bibliography.

Access:

Beach walk from Flinders jetty.

Ownership:

Private land and Crown Land.

Geology/Geomorphology:

The site includes a well defined coastal bluff fronted by a series of low, parallel sand and gravel beach ridges. To the north and south of the bluff sector there are marine cliffs cut in strongly jointed basalt and agglomerate. The cliffs are fringed by a shore platform up to 70 metres wide. The platform has an irregular surface due to uneven weathering of the several lava flows. There are several bowl-shaped depressions on the plateau surface at the top of the coastal bluff which result from landslide activity.

Significance:

State. This is a very clear example of the isolation of a former marine cliff by accretion of beach ridges. The bluffs resulting from this isolation contrast markedly in profile with the adjacent marine cliffs. It is an important site in the context of Victoria to demonstrate this process.


Management:

Class 2. Quarrying of the beach ridge sequence in front of the bluff, or any form of harbour construction should not be permitted on the area of the site.
