Good books about the Australians in WWII

I am going to pick up two more books from the Australian official history series:

• Australia In The War Of 1939-1945 Series 1 Army, Greece,Crete And Syria, Gavin Long.

• Australia In The War Of 1939-1945 Series 1 Army: TOBRUK & EL ALAMEIN, Barton Maughan.
  

Another good book is

• Springboks in Armour, the South African Armoured Cars in World War 2, Harry Klein.
