Coomalie Creek


Coomalie Creek Airfield History


Coomalie Creek airfield was and still is, a World War 2 airfield located in the Northern Territory approximately 90 klms south of Darwin and 15 klms from Batchelor airfield.


This Documentary was produced by Erik Iverson & Xander Rose. They were part of a group of students from America who came to study the Redback Fairy Wren that was known to be habitating at Coomalie Creek Farm.




Almost the same photo as above with Mosquitos from No 87 Reconnaissance Squadron lined up on the Strip.

In the first weeks in November 1942 when 31 Squadron arrived at Coomalie Creek with their Beaufighters, the airfield was still very new, and the workmen were still finishing off the earthworks and a few essential camp buildings. Aircraft had to take care not to collide with machinery or workmen. Each sqn member erected his own tent and dug his own slit trench. That is where they stayed for the duration of their tour. The only essential small buildings were the mess areas, cookhouses, and a storeroom.



Below are photos of some of the rudimentary amenities. In the early days they were whipped up by the Squadron members themselves and as the years went by, were improved as necessary. Sometimes the use and position of the buildings was changed to accommodate different needs and uses.


These are some Campsite photos

Parent Unit; Australian Special Wireless Group
Camped at Coomalie Creek between 1942 and1945. Main role to intercept and record Japanese Army, Navy, and Air Force Kana Signals. Their intercepts were sent to the navy cryptology section in Melbourne via RAAF Signals Darwin. They enciphered their messages to Melbourne in a secret cipher before passing them over to the RAAF Signals personnel. This ensured that their intercepts of Japanese Kana code or encoded messages were not apparent to other military personnel to protect the secrecy of their intercept operationThe Unit played a huge role in the warning of impending Japanese attack on Darwin and shortening the war in the Pacific.

This unit monitored Japanese Wireless signals

On 4 April, 2 battery guns were in action and credited with downing two Japanese Zeros. 1 Battery was first sited at Batchelor where the Headquarters was also located. They fought side by side with the machine gunners of the US 102 Anti-aircraft Battery.

An orderly room, sick quarters and an operations/intelligence room were built using voluntary labour.

ANGLICAN priest Ian McDonald says he knows what indigenous people mean when they talk of “sacred country”: some places just have a strange kind of power, he muses. And this simple chapel at Coomalie Creek, 80km south of Darwin, is one of them. It’s “very peaceful, very moving”, he says; there’s a profound silence that’s punctuated only by occasional birdcalls. It was a different story during World War II, when RAAF Mosquitos and Beaufighters were flying out of nearby Coomalie airfield bound for Timor and Indonesia on bombing and reconnaissance missions. At its height, the camp that sprang up in the bush 2km from the airfield (where the trees afforded some cover from Japanese planes) was home to 450 RAAF personnel. In 1943 they built a small chapel in the camp.




Soon after, a more permanent structure was built

Bush Chapel service


That original chapel is long gone due to fires, white ants and the elements, but in 1992, a replica was built on the very same spot by the present owner Richard Luxton.


For the past decade, Rev McDonald has led a service there on the Sunday closest to August 15.
That date, VJ Day, (victory over japan day), has a special significance for Coomalie. It was from here that the RAAF flew its last sortie of the war (a single Mosquito was halfway to Timor on a reconnaissance mission when Japan’s surrender was announced; the pilot was radioed to return home and performed a spectacular low pass over jubilant scenes at the airfield). Reverend McDonald, says the event’s popularity “has grown and grown”.

Dozens of people now arrive by 4WD or vintage plane – it is still an active airfield – from all over Australia. This year the service included a prayer written by the wartime chaplain, Bill Dunbar, for his congregation on Christmas Day in 1943. You might think a chapel with no walls would be a novel experience for Rev’ McDonald, but in fact his regular church at Freds Pass near Darwin is similarly open to the elements. It sounds pretty quirky. “We get birds flying around our heads during services,” he says. “And sometimes I’ll be giving the sermon and I’ll notice that everyone has stopped paying attention – they’re all looking at a wallaby outside.” What does he do in that situation? “Oh, I’ll look at the wallaby too.” – See more at:

Coomalie Creek Chapel Restoration – Richard Luxton 

An article in THE AUSSIE MOSSIE page 7 by Richard Luxton who is the author of this article and the owner of Coomalie Farm which incorporates the Coomalie airstrip.   Written in 2005

Fifty years ago, when Darwin and its surroundings were in the front line of World War II, the airmen of the RAAF’s 31 Squadron, a Beaufighter unit, were saving to build a bar. What event changed their minds is not recorded, but one of their number a pilot named Butch Gordon, approached Padre Dunbar and told him they had decided to build a chapel instead. The result was of bush timber, clad in corrugated iron, the floor was Compacted earth and the altar steps made from bush stone.
The building was opened in December 1943 with a Cello recital as no organ was available. It was used regularly for services until the end of the war. Bushfires, termites and the climate of the top end took their toll and 50 years on only a photograph of the building, the altar steps and a few sheets of iron remained.
The site of the chapel, the airstrip and taxiway are on Coomalie Farm which I have been developing for the last 25 years between construction projects and lecturing. After meeting many former members of 31 Squadron the decision was made to rebuild the chapel.

Working from a single photograph and the known width of the altar steps, Marc Christianson at the University redrew the building, scaling from the photograph by counting the corrugations on the wall and roof claddings. When excavating footing holes, for the supporting columns (this time of steel to counter fire and termites) charcoal from the original columns was found, proving we had the dimensions correct.   As the frame went up and further photographs were unearthed by 31 Squadron members, we found that two trees next to the building were still there after 50 years.

The construction involved students and staff of the University’s Department of Architecture and Building in working weekends with Mark Smith and Andrew Schulze doing a superb job with the metal fabrication and carpentry. The simple form blends in with the environment and has captivated Architects and designers interested in creating buildings suitable for the tropics. In 1993, the project was entered in the Northern Territory Architecture Awards held by the Royal Australian Institute of Architects and was awarded the J.G. Knight Conservation Award. From there it went to the National Architecture Awards in Sydney and earned the Jury Special Award.

The restoration project is completed and we have identified a nearby concrete slab complete with garden beds and pathways as being the hospital. We are starting on rebuilding this site and it will be available to community groups. Members are very welcome to visit. The airstrip takes aircraft up C130 Hercules….. if you happened to have one.”
