This information has been developed from the publications:

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.

Location	Sunshine- 123075. Former City of Altona. Southern side of Kororoit Creek at the eastern end of the Altona Sports Park.	S2 - Tidal Channels and Salt Marsh, Kororoit Creek Mouth, Altona.
Access	Altona Road and the Altona Sports Park.
Ownership	Crown land
Site Description	The southern side of the lower Kororoit Creek is fringed by salt marsh vegetation dominated by Haolosarcia paragranuloma with an understorey of mostly Sarcocornia quinqueflora.
	The few shrubs of Avicennia marina (White Mangrove) which persist on the southern bank are remnants of a much larger population that originally stretched uninterrupted for 400 m along Kororoit Creek. The marsh is crossed by several tidal creeks including one that is relatively deep and large.
Significance	Regional. The site is a remnant example of the original tidal wetland terrain that was characteristic of the lower reaches of Kororoit Creek. It is one of the few such areas remaining in the City of Altona, and given that the original terrain of the city was dominantly wetland (but not lakes), it is worthy of preservation.
Management	Class 2. The area has been considerably disturbed but the opportunity for practical and useful management exists. The area should firstly be secured from vehicle and trail bike access, either by fencing or by a ditch and bank system. It should not be incorporated into the Altona Sports Park and should not be subject to draining, filling or soil dumping.
