Personally I think it was a mistake for the Army to go for an all-tracked AFV force in the 60s. Keeping a wheeled option available to the Army is one reason I keep banging on about keeping the British wheeled AFVs in service once the M113s started arriving, after all these vehicles were only 10 years old when they started to get retired.
One reason why Project Waler fell over was due to the dilemma over the strategic vs tactical mobility of wheeled vs tracked AFVs and the selection of the ASLAV in 1991 shows the Army fell on the side the wheeled AFV.
Saladins, Saracens and Ferret Mk2s could undertake in 1959 the sort or trials that the batch of 15 LAV-25s undertook 30 years later to demonstrate the value of wheeled AFVs in the Australian context.
It was a mistake, Australia has always needed wheeled vehicles and aviation for strategic mobility.
Look at the ANZAC Mounted Corps in WWI, they had horses, obviously, mostly mounted infantry, but swords were reissued following Beersheba. What most don't realise is they made extensive use of aviation and motor vehicles by WWI standards. Australia didn't operate them but there were also tanks in theatre. Chauvel was pushing for the motorisation of the army after the war; actually, he wanted the government to repatriate the vehicles we had paid for and been using in Europe and the Middle East.
They didn't need to be fancy; armour kits for trucks designed to fit them would have sufficed, and we could have built them locally.
We had Staghound Armoured Cars, Daimler and Ferret Scout Cars, in addition to the small number of Saladins and Saracens. We could have easily justified the local production of something perfectly adequate.
Motorising the CMF is easy; a transport, motor or mech troop provides company lift, and a squadron lifts a battalion. Each Brigade could literally have a Service Corps Regiment (possibly integrated or even reserve with a regular cadre) to do just that. The important thing is having the depots and the trained personnel, as well as something for them to work on, build and maintain their skills. The gear doesn't need to be the latest and greatest; it just needs to be usable.
CMF CAV would handle the tactical reconnaissance mission for their brigade; this is where the CVRT would excel, possibly each Regt could have a CAV Sqn with CVRT and an APC Sqn, maybe even a tank Sqn as well (this would fit the Infantry division scale of equipment, i.e. one tank Btn/Regt per Division).
An Armoured Cavalry Regiment (US type) is a Corps level capability; there logically would be one, and it would have at least one regular Squadron. This would be Wheeled for strategic mobility.
Now, if I had Visio, as I do at work, I could sketch a structure up.
Basically, mobility, including wheeled APCs are a Service Corps function.
Tactical rec is primarily and CAV function with tracked vehicles
Organic rec is a function of the unit, and is wheeled, Scout Car, Armoured Car, 4x4.
I need to think about it more. I did some work years ago, mostly in structures I set up in a buggy old game, that sucked as a game but was great for building force structures (I cannot remember the name of it). Basically, I built what I saw as the ultimate Australian Army of the early 90s, which, of course was based on what was in existence in the 70s and 80s.
Found it, Patriot. I will see if I can find it somewhere to download is it was great for building armies. It had a library with basically all the good Cold War gear from the 50s to the 80s.
