On the heels of yesterday's test of Indian/Socotra emergency reinforcments, I decided to also test Tasmania as a trigger for Oz reinforcments. Both targets are islands, both are past the x,y trigger line for their respective theater. Socotra did not trigger reinforcments for India.
An invasion of Tasmania, OTOH, DID trigger reinforcments for Oz.
Methodology:
1) Using the same test-bed game as yeasterday, I loaded an earlier save just after Singapore fell, but before the Socotra invasion TF launched. I loaded a small amphib Tf there with one full, and one partial, infantry regiment, and sent them on a Direct route to Perth. I wanted to verify that Perth WILL NOT trigger reinforcments. It should not based on x,y coordinates vis a vis the believed trigger line around the latitude of Brisbane.
2) After a transit of about ten days, the TF landed, attacked, and took a cleaned-out Perth. No reinforcments were triggered. I refueled, reloaded a smaller TF than before, and launched it on Direct to Launceston, Tasmania. While in transit, I sent the lone xAP there to mainland OZ, placed the one defense unit on Strat to cripple it, and changed its planned destination to Canberra to further weaken it.
3) The Japanese TF landed and attacked, but did not take Launceston on the landing turn. However, this attack DID trigger emergency reinforcments, as seen in this Ops Report:

Conclusions:
1) When it comes to islands and triggering, not all islands are created equal.
2) Extrapolating, any base of any size, south of the Brisbane-area trigger line, should trigger reinforcments.
3) The Oz reinforcments come onto the board at less advantaged locations for the Allies than do the Indian emergency units. Long transits will be necessary to bring them to bear versus trivial transits from Aden to Karachi.
4) The units are pretty typical (I don't want to post ten more jpegs.) The emergency supply convoy arriving at Cape Town has this composition:
