We had vast pooled Ordnance stockpiles in Malaya and Australia used UKrifles, Brens and some vehicles while the poms used Australian
Owens (for a strategic reason though) and International trucks and a lot of ammunition. All the pom kit was left behind when they left except for, once again, some 'materials of strategic or of warlike importance' kit. Why this kit included Land Rover light ambulances, clapped out Bedford RL chassis type fire engines and busses heaven only knows. Australia/NZ and S Africa took the Centurion tanks whereupon SA immediately sold their share to Israel! The R.Naval dockyard were the only place that could load and unload the 60 ton tanks
Where were we..... ah yes....., that's why Australia used and inherited a monster load of pom kit in the early 70's
