Australian Spy Museum

28/08/2026

Australian Spy Museum has some more events coming up - the afternoon of Tuesday 27th October we are at Sydney Mechanics' School of Arts with the film "The Imitation Game" followed by a Q&A talk and demonstrations. Tickets at link below.

Also in October we'll be having our first exhibition at a gallery in Sydney's Inner West - if you'd like to be first to know what we are up to follow "Australian Spy Museum" on Facebook, Instagram, Threads or Bluesky.

An afternoon of cinematic brilliance followed by top-shelf espionage history!

Yes I know - it's been weeks since our last "Featured Artefact" post. Its worth the wait though and relevant to our presentation for RUSI NSW in Sydney next Tuesday.

John Anthony Walker was head of the infamous Cold War Walker Family spy ring - the worst known compromise of US Navy crypto and other secrets. Born in 1937 and a Catholic altar boy, by his mid teens Walker was a bit of a tearaway and then stupidly joined a friend in some minor burglaries. On his court appearance an older brother in the Navy intervened, and convinced the judge that John should join the Navy instead of being sentenced.

Walker served as a radio and crypto specialist on multiple ships including the launch crew of US Navy nuclear submarine Simon Bolivar, and developed a keen sense of what was valuable. After retiring in 1974 he recruited a colleague, an uncle and then one of his own sons into the spy ring. He even attempted to recruit a daughter in the Army but she rebuffed the offer.

Walker stole and sold to the Soviets huge amounts of material:
- Copying so much that he wore out Minox cameras (I've included a rarer black one here) pictured on a US burn bag
- He then tested an 8mm film camera with single frame function, and recommended this method to the KGB
- He simply handed over large volumes of original documents - the FBI found 15 kilos of material at his last dead drop site
- And the Soviets also gave him a device that could read the wiring settings of US Navy rotor-based cipher devices, which along with key material led to catastrophic compromise of ciphered traffic. This was a driver for later adoption of devices like the pictured KG-84 cipher machine which used a keyfill device so no human held the keys. **

The motivation was money - Walker liked the nice cars and meals that Soviet cash and silver bullion bought him. There were multiple chances to catch him earlier, providing "lessons learned" for today:
- Walker observed that sensitive data onboard was always under two sets of eyes - until headed for destruction in a burn bag - so he took over that task
- Walker's wife spoke to FBI providing details of his activities, but it was written off as a domestic dispute - simply amazing in hindsight
- His relatives - despite their own military oaths - joined him in espionage activities for relatively small financial rewards

** Our KG-84 is (obviously) de-milled - we sourced an empty chassis that was externally cosmetically OK to illustrate this story.

It’s going to be a busy week - with two displays at the University of Sydney and this demo and talk at the ANZAC Memorial in Hyde Park next Tuesday. Really looking forward to this event.

Sydney needs more "Nerdy Things to Do" especially for young people.

As part of the Science Week activities at Chau Chak Wing Museum I'm offering a 40 minute Enigma machine demo talk (book a ticket below) and following that a more casual display & blitz talks.

As part of SMRI’s Science in the Museum event, Mike Pritchard from the Australian Spy Museum will conduct a live demonstration of a configured Enigma machine.

We are trying something new with a "spycraft show and tell" at Dulcies cocktail bar in Kings Cross. You book via Dulcies website but will need to be fast its a small venue.

Australian Spy Museum Featured Artefact this week is from the Cold War's Ground Zero - a 1981 Stasi infrared camera surveillance briefcase.

This rare artefact is a step up from the unit I shared here a couple of months back, as it uses a later all-electronic camera and is fully optimised for covert night photography.

More interesting to me is how these artefacts embody in a really tangible way both the intrusiveness of the authoritarian nation state, (and) the creativity and skills of the OTS engineers that build intriguing spycraft tools. So you can appreciate them on multiple levels and in that lies the ability for a spy museum to build something really unique.

So how does it work?
Photo 1 - On the outside of the briefcase are:
- A fake briefcase latch - behind it is the infra-red camera lens
- A faux leather exterior - behind it are three infrared flashes

Photo 2 - Inside all components are mounted on an inner frame:
- (Centre) The infrared camera body
- (Top right) Large battery box, that goes into
- (Bottom) A distribution box - that splits the power out to
- (Left, and Photo 3) Three infra red flashes
- (Top) Small black power supply for the IR camera, that is switched on / off via a white cable that runs to:
Photo 4 - The shutter release microswitch, concealed in the handle so the operator can take pictures just by moving their thumb while holding it

Photo 5 - Factory IR Camera field delivery kit - these were provided to OTS regional staff who could custom fit them into any mission-required concealment - like the custom flower box I showed here about a year ago.

When the Imitation Game met Harry Potter

is at this afternoon and there are thousands of people here for graduation (congrats to all).

It took a bit of patience to get a suitably moody pic with no bystanders, made easier by the already monochrome sky.

Recently we acquired more Australian Womens Army Service (AWAS) uniforms for our WWII women codebreakers collection.

Alongside British WRNS and US WAVES uniforms these remind us how Australian women took on technical and analytical work while men were at the front. Among other groups University of Sydney students were recruited as AWAS operators, while academics helped in the early war cryptanalytic efforts at Fleet Radio Unit Melbourne or FRUMEL.

Around 600 women of the Australian Women's Army Service (AWAS) served at Central Bureau (CB), in a secretive tri-service intelligence unit comprising Australian, American, and British forces. AWAS grew into technical and intelligence-heavy positions, to manage the influx of Japanese signals intelligence (SIGINT) across the Southwest Pacific Area.

The scope of AWAS work at Central Bureau spanned the entire intelligence cycle, including intercepting Japanese Morse (Kana), traffic analysis, and cryptanalysis. They were primarily tasked with breaking tactical military and transport codes, most significantly the Japanese Water Transport Code.

AWAS staff operated IBM Hollerith punch-card machines, that enabled the women to sort, count, and cross-reference millions of intercepted code groups to find the "depths" or repetitions needed to break a cipher. Additionally, they used Typex cipher machines and specialized "kana" typewriters to transcribe intercepted Japanese messages. The sheer volume of messages in itself created a new intelligence source via the discipline of traffic analysis, obviously relevant to cyber / network security today.

Central Bureau’s most famous achievement was its pivotal role in the downing of Admiral Isoroku Yamamoto in April 1943. AWAS personnel were instrumental in processing and decrypting the specific signal that detailed the Admiral's precise flight itinerary, which allowed US P-38 Lightnings to intercept and destroy his aircraft. (On that note we have some nice items related to the Yamomoto mission but they are at the bottom of a pile in our storage, so we'll save that for another time).

For those interested to know more "The Secret Codebreakers of Central Bureau" by David Dufty is a good read.

Sydney-based and interested in espionage and spytech history?

We're a private organisation with a massive collection of items from the history of espionage around the world. We're looking to pivot into a physical home but for now you can follow us here for updates and enjoy browsing the huge catalog of items we have already posted

Australian Spy Museum's Featured Artefact this week is one for the AV pros, and a recent addition to our stunning collection of agent recorders - an early 1970's Alpha One.

Made in the US by Amerex for the IC, the Alpha One succeeded the 1960's EDI mini reel to reel units used by allied agencies including ASIO.

Solid contender for a favourite cold war micro recorder.

Australian Spy Museum Featured Artefact this week is a KGB Nyrok camera specially designed for Kompromat photography - that is, capturing extortion material to use against Western diplomats and corporate types.

Decades before Epstein was compromising the most powerful people in America for a foreign intel agency, the Soviets mastered this dark art.

Nyrok was designed in the 1960's by specialist photo-technical staff of the KGB's Operational Technical division, and then produced in the state-owned KMZ photo-optical factory.

To use this camera a field team first gets access to an adjoining or upstairs room and slowly drills a hole through brick / ceiling until just short of the final millimeters of plaster and wallpaper. The final hole through the wallpaper is drilled with a 1mm bit, and the specialist Kompromat lens then opens up a "fisheye" view into the target room. Westerners were directed into specific hotels with some suites already bugged and prepped for Kompromat.

Of note - the camera is fixed-focus with great depth of field, but you'll see that the observation viewfinder has an adjustable focus.

Second, there is a lever mounted on the front-right side of the body - this is a mirror-position lever. When in the default forward position the view is directed up into the viewfinder for observation. When pulled forward to take photos, it directs the view through the shutter into the camera to record images.

As for the sign "Covert Road" - yes its a real US street sign - but not related to a KGB case. I bought it as the name was irresistible and it would make a fun bit of "scenography" in a spy museum one day, so here it is.
