Gina you’ll find some useful background material in the work of art historian Ann Elias:

para 3:
By 1942 there were so many protests − particularly from the Army − about Dakin’s interference in military matters that a new arrangement had to be made. Finally, each of the services took control of its own camouflage operation, leaving the Defence Central Camouflage Committee to act as their advisory body only. The camouflage research station at George’s Heights, set up by the Department of Home Security for experimentation, was handed over to the Army.
para 21:
Early in 1942 the Army separated from the camouflage organisation set up by the Department of Home Security. This was certainly no loss to the Army since it had always trained its own camouflage officers, either at the Camouflage Wing at George’s Heights organised by the Army School of Military Engineering, or through camouflage training units run by the Royal Australian Engineers.
“Once the army had decided to go its own way, the Department of Home Security soon found that its camouflage activities were mainly confined to the R.A.A.F., for after October 1942, when the threat of Japanese invasion had disappeared, all civil camouflage was discontinued.” (Camouflage Australia, Ann Elias 2011)
Her book Camouflage Australia contains some excellent photos with file refs that may yield info on the development of DHS camo colours and patterns.
