Flock of seagulls at The Cheetham Salt Works (upper right corner). “The Cheetham Salt Works (former) was established in 1924 and operating until 1990, at Point Cook Road, Laverton. Although no longer used as an operating salt works the regime of maintaining variable water levels throughout the complex system is still maintained by Parks Victoria in its present role as a wetland environment and hence the original processes can still be interpreted today.” ( heritagecouncil.vic.gov.au)
