The headwaters of the creek rise between Calvert Hills and China Wall in the Northern Territory and flows in a north easterly direction.

It flows through mostly uninhabited plains country through Wollogorang Station then crosses the border into the northwest region of Queensland and later discharges into the Tully Inlet and then the Gulf of Carpentaria.

[5] 31 species of fish are found in the creek, including the glassfish, barred grunter, silver cobbler, milkfish, fly-specked hardyhead, treadfin silver biddy, golden goby goby, barramundi, oxeye herring, mangrove jack, chequered rainbowfish, bony bream, catfish, Hyrtl's tandan, freshwater longtom, seven-spot archerfish and the gulf grunter.

[6] The traditional owners of the area are the Ganggalida and Gananggallanda peoples who know the creek as Wollogorang which in their language means "happy running waters".

Settlement Creek, Morning Inlet and the Gregory and Staaten rivers were all being considered for the extra level of protection with property owners being advised of the plan and given time to comment.
