[1] The jetty is located at Naval Base and accommodates ships unloading bulk caustic soda and loading refined alumina.

[1] The jetty, almost 500 metres (1,600 ft) long, is home to Kwinana Bulk Berth 2 (KBB2), and facilitates ships loading and unloading bulk products such as cement clinker, mineral sands, silica sands, coal, iron ore, bauxite, gypsum, nut coke, slag and various other commodities.

The overall conveying system has a maximum rate of 1,500 tonnes (3,300 thousand pounds) per hour and is connected to rail through standard and narrow-gauge to conveyor.

[5] The jetty was originally owned by BHP as part of its local steel works but sold to Fremantle Ports in 2002.

[1] The single-berth jetty can load grain at up to 5,000 tonnes (11 million pounds) per hour and has a berth length of 291 metres (955 ft).

[3] A report by the Western Australian Government Westport Taskforce released in August 2019 proposed five options for the Fremantle Harbour, with two advocating shared container trade between the Inner and Outer ports, and the other three proposing a new stand-alone container port at Kwinana.

At the time of the report, the Inner Harbour handled 700,000 units of a theoretical capacity of 2.1 million, being restricted by road- and rail access in and out of the port.

The Outer Harbour option eliminated this restriction but required additional road and rail development.

[11] It also led to resistance from the Maritime Union of Australia, MUA, which feared that the new facility would lead to job losses at the Inner Harbour.
