The Fortress Newcastle Project 2020

A coalition of several community groups, heritage researchers, University of Newcastle and other stakeholders is conducting research, to produce a multi-format resource for development of enhanced public awareness, interpretation of remnant sites and visitor experiences of the story of Fortress Newcastle.


What is Fortress Newcastle?

At the commencement of World War 2 Newcastle was the location of Australia’s largest integrated steel-making facilities, many associated heavy industries, various minor industries, many coal mines, a busy deep harbour for merchant shipping, floating dock, ship building dockyard and critical production infrastructure.

The Hunter Region became Australia’s major industrial production hub for manufacturing and supplying a massive range of essential war related products, making it the most important location for mainland defence.

The military operation to defend these vital industries became known as ‘Fortress Newcastle’ – the largest military defence establishment in Australia’s history.

What did Fortress Newcastle Defend?

Fortress Newcastle extended from Port Stephens in the north, south to the Tuggerah Lakes and west to Muswellbrook.

The key points to be defended were the entrance to Port Stephens itself, the whole of the Stockton Bight beach between Anna Bay and the entrance to the Newcastle Harbour, and the beach areas south to the entrance of Lake Macquarie.

In December 1941, this area was defended by four fixed coastal defence forts, two major air bases and four army accommodation and training camps.

The Four Forts

Tomaree at the entrance to Port Stephens, Fort Scratchley at the entrance to Newcastle Harbour, and the Park Battery, located on the high ground at the southern end of King Edward Park in the city, all were armed with two six-inch (150 mm) calibre guns. Fort Wallace at Stockton was armed with two 9.2-inch (240 mm) calibre guns.

The guns at all forts, except those at Fort Tomaree, were capable of firing inland as well. A much smaller fortified position, located on the Breakwater at Nobbys, was armed with a six-pounder (2.72 kg) gun to control the entrance to Newcastle Harbour.

Royal Australian Air Force Radar Stations were positioned on the summit of the Tomaree Headland, Park Battery in Newcastle, Ash Island, Catherine Hill Bay and Wipers near Williamtown Air Base to provide electronic surveillance over the sea and air approaches to the Newcastle Defended Area.

The Tomaree Fort also included a torpedo-launching system and 18pdrs that could cover the whole of the entrance to Port Stephens. Also at Nelson Head next to the inner lighthouse inside the port was armed with 60pdrs.

The Royal Australian Navy established a port examination service in Newcastle Harbour to check arrivals and departures of all shipping.

A naval transit station, HMAS Maitland served as the port’s war signal station, harbour defences and general security, and providing convoy support.

At the entrance to the Newcastle harbour for its defence an indicator loop was laid seawards from a minefield with the indicator loop and minefield controlled from a building located on the Stockton foreshore.

The Royal Australian Navy constructed a 5000-ton oil fuel tank at Tighes Hill, together with the installation of the necessary oil-loading pipework connection to provide a fueling capability for naval ships based at or visiting Newcastle Harbour. A southern defence line was established with an anti-tank ditch at Cold Tea Creek, south of Belmont.

A Naval base, HMAS Assault was established at Nelson Bay, to train American and Australian landing craft boat crews and beach commandos.

Army accommodation and training camps were located at Rutherford, Largs, Greta, Gan Gan and Singleton to provide accommodation and a training area for three to four thousand men.

Anti-aircraft batteries were positioned at Tomago, Fern Bay, Mayfield, Stockton, Wangi as well as other very mobile batteries, easily relocated in and about the approaches to Newcastle and its industries. The RAAF operated air bases at Williamtown north of Newcastle and a large seaplane base at Rathmines at Lake Macquarie south of Newcastle

5 thoughts on “The Fortress Newcastle Project

  1. Shepherds Hill Gun Emplacements were linked with Fort Scratchely and Fort Wallace for the defence of Newcastle Harbour entrance. The Master Gunners Quarters at Shepherds Hill housed both the Master Gunner & his family along with the Gunners. During WW2 the site was covered in timber buildings for military use which were removed at the end of the War. Newcastle Council commissioned a CMP for the whole site which was completed in 2019. This document provides detailed information about the site and its construction and use.

  2. This is an important part of our 20th century history. I remember taking students from Nelson Bay High on hikes up Tomaree peering at then ruins of the gun emplacement decorated by graffiti! And a photo from the Percy HASLEM collection reminding me that in early 1986 when I was first at NBHS I went off to Neath and other parts of the Hunter Valley to an Indigenous sites sites tour led by Perc (a speaker of the Awabagal language) and two senior Wonnarua/Darkinang men. The only thing in this article with which I take exception is at the very start – the quotation attributed to D.O. Morris in 1947 – the old so-called “Zombie Myth” that the Japanese intended to invade Australia. It has served US interests in maintaining and further establishing military/spy bases – at no cost to themselves – ever since! Australian historian Humphrey McQueen published his research on this “belief” late 1980s/early 1990s around the time I was beginning a lengthy period of teaching in Japan myself.
