Cockburn Sound

Parmelia Bank is a sandbank to the north of Cockburn Sound, off Fremantle, Western Australia within the limits of the Fremantle Outer Harbour. The Parmelia Bank is named after the barque Parmelia, which grounded on the sandbank in 1829. Parmelia Bank, south of Success Bank, is a slightly smaller bank than the latter and runs approximately parallel to it, about 3 kilometres (1.9 mi) further south extending from Woodman Point, almost to Carnac Island; it also is within the designated Fremantle Outer Harbour. The channel through this bank is likewise named after the bank – Parmelia Channel that leads into Cockburn Sound. During World War II, Parmelia Bank was the location of the anti-submarine boom net protecting the northern access to Cockburn Sound. From Woodman Point, the barrier ran west on top of the bank, stretching to Carnac Island. A dredged channel, the location of a gate in the barrier, let through the sandbank into Cockburn Sound. From this channel, the barrier ran south-west to Garden Island. The Success and Parmelia Banks were formed during the Holocene, more than 10,000 years ago, through the deposition of sediment which had been eroded from the Rottnest Shelf and the Garden Island Ridge. Success Bank was formed in the lee of Mewstone Rocks while Parmelia Bank was formed in lee of Carnac Island.

Woodman Point is a headland on the west coast of Western Australia. It is located in the Perth suburb of Coogee, 22 km (14 mi) south-south-west of the city centre and 8 km (5.0 mi) south of Fremantle. It extends westward into the Indian Ocean. The coastal waters immediately to the north of the point are known as Owen Anchorage, while to the south is Jervoise Bay. Woodman Point marks the northern extent of Cockburn Sound. Woodman Point is contained completely within the Woodman Point Regional Park, a 54-hectare (130-acre) regional park with recreational facilities including parklands, playgrounds, jetties, and a caravan park; and historic sites including a World War II prisoner-of-war camp and World War II munitions bunkers. The remnant vegetation of the area was documented by Robert Powell and Jame Emberson in the book Woodman Point: a relic of Perth's coastal vegetation in 1981.

Henderson Naval Base was a proposed and partially built naval base of the Royal Australian Navy south of Fremantle, Western Australia in what is now the suburbs of Naval Base and Henderson. Planned in 1911, construction of the base commenced in 1913 but was abandoned during World War I and cancelled in 1920. Temporary naval facilities subsequently existed in the state during World War II but a permanent facility was not established until 1978, when HMAS Stirling was commissioned.

HNLMS K VIII was one of the three K VIII-class submarines of the Royal Netherlands Navy, built to serve as patrol vessel for the Dutch colonies. Launched in 1922 the boat saw service at the start of World War II, before being decommissioned in 1942.

The Australian Marine Complex (AMC) is a marine industry precinct located at Henderson, Western Australia, 23km south of the Perth CBD. It is located on Cockburn Sound.

Challenger Battery, also referred to as J Gun Battery, is a heritage-listed battery at Entrance Point, Garden Island, Western Australia. Historically, it has is also been known as Garden Battery, Entrance Battery and, finally, Challenger Battery. It was added to the Australian Commonwealth Heritage List on 22 June 2004. It was part of the Coastal defences of Australia during World War II and the Fremantle Fortress, protecting Fremantle Harbour.

SS Alacrity was a tug built in Graville, France in 1893 as Jean Bart and was operated by the Dunkirk Chamber of Commerce. She was sold in 1902 to Howard Smith and renamed Alacrity for tug service in Port Phillip, Australia. During the First World War, she was purchased by the Royal Australian Navy in 1917 for use as a patrol vessel, inspection vessel, and minesweeper based at Fremantle. She was never commissioned. After being sold in 1925, she was slated for breaking up and was moored in Jervoise Bay, Western Australia, until a fierce gale in Cockburn Sound wrecked her in 1931.

Kwinana Power Station (KPS) was Synergy's second-largest power station, located in Naval Base, Western Australia within the City of Kwinana. At its peak, power was produced from six turbines driven by steam from boilers fired by coal, natural gas or fuel oil, and one gas turbine. The steam turbines closed in 2015; however, two gas turbines continue to operate on the site. This is not to be confused with Cockburn Power Station to its immediate south. KPS was originally built in 1970 as an oil-fired power station, however it was later converted to coal due to the rising price of oil caused by the 1973 oil crisis. This project received an 'Engineering Excellence Award' from the Institution of Engineers Australia (Engineers Australia) in 1980.A 20 MW gas turbine, able to be operated on natural gas or diesel fuel, was added in 1972 and took the total nameplate rating to 900 MW which was the station's peak. With greatly increased availability of natural gas from the North West Shelf Venture project, natural gas firing was introduced in the mid 1980s. In 2005 oil burning was re-introduced making the power station unique in Western Australia as it could burn the three fuels: coal, natural gas and oil. The original station operated: Two 120 MW steam turbines (oil/gas/coal fired) as A units 1 & 2 from 1970/1 to September 2010 Two 120 MW steam turbines (oil/gas/coal fired) as B units 3 & 4 from 1972/3 to December 2008 Two 200 MW steam turbines (oil/gas/coal fired) as C units 5 & 6 from 1978/9 to October 2015 One 20 MW gas turbine from 1972

Cockburn Power Station (CKB) is a power station in Naval Base, Western Australia within the City of Kwinana. The station was commissioned by Western Power Corporation in 2003 and is immediately south of the closed Kwinana Power Station. It has a 160 MW natural gas powered Alstom GT13E2 gas turbine which provides steam to an 80 MW steam turbine that together generate a total 240 MW of electricity. It was the first combined cycle gas turbine power station in Western Australia. It came under the control of Verve Energy in 2006 when Western Power was split, and since 2014 has been under control of Synergy.

The Fremantle Outer Harbour is the part of Fremantle Harbour located in the Cockburn Sound, at the City of Kwinana, Western Australia. Fremantle Harbour consists of the Inner Harbour, which is situated on the mouth of the Swan River; and the Outer Harbour, which is 20 km to the south. It is managed by the Fremantle Port Authority. The Outer Harbour's creation dates back to the Stephenson-Hepburn Report and was initiated in 1955.
