When the AC1 Sentinel becomes available, please note that it was only for training purposes and Australian homeland defense -- it was never used in combat, but it was available in case Australia was invaded.*
*
Also note that care must be taken to purchase the appropriate tanks for the specific Theater the scenario takes place in, if one wants a historical setup.  ANZAC forces were in North Africa, Italy, Europe, The Middle East, South Asia, The Pacific -- and in each Theater had a distinctive composition.*
*
Generally speaking, the more advanced tanks for the time period will be found in North Africa, Italy and Europe, and those tanks that have generally outlived their usefulness will be found in The Middle East, Asia and the Pacific.  Also, British tanks (including a predominance of Lees) will be found North Africa and The Middle East.*
*
Note that the American tanks will be more common in the Pacific than in any other Theater.  Likewise you will find Stuarts in the Pacific, and Honeys in North Africa.  Lees were shipped to India and Australia when they outlived their usefulness in North Africa, as were Valentines and Matildas. Many Grants came directly from the USA to Australia, but were first modified by the Australians before deployed.  The Australians had some 16 modifications made to the Grant over its long life in Australia, including adding Sherman suspension, radio equipment, smoke launchers and applique armour*
*
In the Pacific, Australia had numerous Lees and Grants, Matildas and Stuarts, while in North Africa they generally had Mark VI's, Honeys, Crusaders, Valentines and Matildas.  However, at times the number of captured tanks in use outnumbered the British tanks handed down to them.*
*
New Zealand had mainly Valentines and Stuarts in the Pacific, and exclusively Shermans in Italy (no tanks in North Africa).*
*
In the peripheral Theaters like The Middle East, the most outdated equipment will still be found -- the Light Tank Mark VIb, for example, can still be found as the main armoured unit of the Australians in Cyprus while at the same time the New Zealanders were using Shermans in Italy.*
