The original proposal was to subdivide Lot 6 Old Coast Road into eleven lots ranging in size from 2 hectares (ha) to 6 ha each. During the public review period for the draft criteria, the proponent modified the proposal and now proposes to subdivide Lot 6 into 9 lots averaging approximately 4 ha.

The proposal is located within the Lake Clifton catchment area. Lake Clifton is one of the most significant wetlands in Western Australia due to its international importance as a waterbird habitat and because it contains the largest known example of living microbialites in a lake environment in the southern hemisphere.
