Hi All, Just a fun one from the land down undahhhhh. The Australian Signals Directorate (government code people) are celebrating their 75th anniversary by releasing a limited edition 50 cent coin that is inscribed with codes. There are 4 standard codes on the coin, each informing the next, and a 5th bonus layer. It's right up our alleys! It took me a couple of days to get through the codes... The asd story is here: www.asd.gov.au/75th-anniversary/news/2022-09-01-75th-anniversary-commemorative-coinand higher res images in this story: www.abc.net.au/news/2022-09-01/act-spy-agency-releases-coin-with-secret-code/101391964You can leave your answers on the ASD link above. Not sure if you get anything, but they can be entered in there. As a bonus for those looking for a challenge, their REDSPICE info pdf has a code on the final page. It took me a little while to get through it, but if you go to this page: www.asd.gov.au/about/redspice and look through the pdf in the link you can find everything you need. Enjoy!

FYI, the 5th layer (bonus) that they talk about in the video being not cracked has been cracked... I've submitted it and it can now be found on reddit.

Answers time! If you don't want to know the answers, turn the TV off now!
1) The symbols under "Elizabeth II Australia" are braille- ABCDEF. These give an ordering to the letters: BTHASA -> ATBASH; 2) Outside ring of other side
Use ATBASH on outside ring...
WE ARE AUDACIOUS IN CONCEPT AND METICULOUS IN EXECUTION.
FIND CLARITY IN 7 WIDTH X 5 DEPTH.
3) Inside ring
Organise letters in two 7x5 grids and read downwards:
BGOAMVO EIATSIR LNGTTNE OGRERGX NTEAIFC
ECAIEOA LEKFNR5 LWEFCHD EEAEEE7 NMDRXX5
BELONGING TO A GREAT TEAM STRIVING FOR EXCELLENCE WE MAKE A DIFFERENCE XOR HEX A5D75
4) Hexadecimal 0-9A-F on coin
XOR operation the hexadecimal with "A5D75A5D75" doubled version of previous clues
For 75 years the Australian Signals Directorate has brought together people with the skills, adaptability and imagination to operate in the slim area between the difficult and the impossible.
5) Inner and outer ring colours
Outer ring is Morse code, including the dots... The lined ones are the spaces
.---- ----. ....- --... -.. ... -... .- .-.. -... . .-. - .--. .- .-. -.-
1947DSBALBERTPARK (1947 DSB Albert Park- the date of the first incarnation of the ASD, and the location)
The inner ring is binary: 1000001101001110001001000011110001011100100110010011000001100100110010
