answer: Brown Hill Creek
context: Title: Gawler West, South Australia
  Passage: Gawler West, (postcode 5118) is a suburb of the South Australian town of Gawler, located in the northern Adelaide metropolitan area region, 43 km north of Adelaide.  It is bordered by the Gawler River and the Gawler railway line and the suburbs of Gawler South, and Evanston.

  Title: Division of Hindmarsh
  Passage: The Division of Hindmarsh is an Australian Electoral Division in South Australia covering the western suburbs of Adelaide.  The division was one of the seven established when the former Division of South Australia was split on 2 October 1903, and was first contested at the 1903 election, though on vastly different boundaries.  The Division is named after Sir John Hindmarsh, who was Governor of South Australia 1836-38.  The 78 km² seat extends from the coast in the west to South Road in the east, covering the suburbs of Ascot Park, Brooklyn Park, Edwardstown, Fulham, Glenelg, Grange, Henley Beach, Kidman Park, Kurralta Park, Morphettville, Plympton, Richmond, Semaphore Park, Torrensville, West Beach and West Lakes.  The international Adelaide Airport is centrally located in the electorate making noise pollution a prominent local issue, besides the aged care needs of the relatively elderly population − the seat has one of the highest proportions of citizens over the age of 65 in Australia.  Progressive boundary redistributions over many decades transformed Hindmarsh from a safe Labor seat in to a marginal seat often won by the government of the day.
  Title: Grand Junction Road
  Passage: Grand Junction Road is the longest east–west thoroughfare in the Adelaide metropolitan area, and is located approximately 9 kilometres north of the city centre.

The western terminus is at the intersection of Old Port Road, 300 metres east of a causeway, which separates the Port River from West Lakes.  The 2.4 kilometre section of road that continues west of Old Port Road to Semaphore South is named Bower Road.  The eastern terminus of Grand Junction Road is in the suburb of Hope Valley, at the intersection of Hancock Road and Lower North East Road, just before the latter proceeds into the Adelaide Hills, past Anstey Hill Recreation Park and on towards the towns of Houghton and Inglewood.
