Ok then the public and politicians don't care about armour. I don't know or understand why but from history it appears to be the case. This is not a party political thing it is an observation of what has happened under successive governments for decades. They seem to take turns at disappointing the RAAC.
I agree with what you are saying ref the expenditure on other capabilities but unfortunately some extremely important, even critical capabilities seem to miss out. Armour is one, artillery another and believe it or not RAN minor warfare vessels fall in that basket too. They are critical but do not have the profile or support they should have and often have to make do with old, worn out or just plain unsuitable equipment when mind blowingly obvious alternatives are both affordable and available.
Why do we only have 59 Abrams in two squadrons when a third would cost so little? Why do we have the M-A1 AIM SEP when the M-1A2 is so much more capable , available and affordable? Why didn't we get AIFVs 20 years ago? Why don't we have SPGs when they offer so much capability for so little comparative cost? Why are MLRS and HIMARS out of bounds for the ADF when they have been proven so valuable in service with out allies? Why was the M-113 upgraded instead of being replaced a decade or more ago? Why was the ASLAV upgrade cancelled? Why wasn't an interim replacement considered when operational needs were impacting the number of vehicles available for regular activities? Why wasn't the Army motorised / mechanised in the past when just about every generation since Chauvel has recommended and pushed for it?
Like I said, I am often wrong and hope in this case that I am but history shows that the ADF does not do well when it comes to getting armour procurement projects off the ground. I was meant to be part of the Project Mulgara trials in the late 90s, its now 2014, I have been out of uniform for 15 years and LAND 121 Phase 4 looks to finally be about to provide something to fill that capability identified twenty years ago, that's one of the good news stories, the second Armoured Regiment rumoured when the Army moved north never happened, the old pams mentioned the second regiment as well but it never existed.
I am not for one second saying LAND 400 should not go ahead, I just fear that there will be delays, issues and cost cutting. Personally I would rather see more spent, not less, I would love to see some niche capabilities in addition to LAND 400, armoured engineering capabilities, some form of armoured amphibious capability, SPGs, SP mortars, more MBTs (enough to have a separate full strength tank regiment and sufficient extra vehicles to support the ACRs). Acquisition of something akin to the Viking or Bronco would be good to support light and amphibious forces, it wont happen though. All affordable, justifiable just cant see any of it happening.
Just to reiterate, I do hope I am wrong.
