SuburbBrooklynTypeOtherDetailsOn the western shore of the Hawkesbury at the southern entrance to Porto Bay south of Brooklyn. This is a very common name in the lower Hawkesbury region as well as in Sydney Harbour and elsewhere. In almost all cases it relates to places that have a low rocky shore and thus can readily be used as a landing place. There is also usually evidence of an Aboriginal midden and an early European house site nearby, indicated by some exotic plants and a general absence of thick bush.
The latter results from excessive nutrients in the soil from human wastes. These locations tend to be characterised by coarse grasses and appear green in contrast to the surrounding bushland. At this location at Porto Bay the name was used in 1835 when James Branan received a land grant. An industrial miner's right was granted for this area on 12 December 1893. Mullet Creek was the site of a search for coal in the 1870s.
