The U.S. Army has been working with the Abrams intensively since the early 1980's. The Australians probably don't want to get overwhelmed by getting too much information too quickly from the Army -- it's better to start slow and go from there.

Uh... the Australian Army has been operating tanks since WW1 so it's not like we don't know anything about armour ops (hell, we exchange armour instructors all the time). I suspect it is because the Marines operate their tanks like the Australian Army does.
