Hi Peter,
Dave has answered the question rather better than I could.
One of the challenges of Pluto occultations is that predictions are working at their limits to narrow the path down beyond a hemisphere of earth ... i.e. if you are in the southern hemisphere, then it's likely that you will (may) see the occ.
The MIT crew prediction for this event is for Tassie, NZ, and Antarctica.
The RIO prediction is for Darwin to Port Pirie.
The UCAC4-DE432 prediction is for southern Australia and NZ.
They cannot all be right. But simply by observing we can pin things down a lot more than by not observing. This is where amateur telescopes are of such utility - a mag 12 occ is eminently doable by most 8" scopes, an integrating video camera and a video time inserter. Scatter those telescopes over Australia and NZ, and you can add to the storehouse of scientific knowledge .
Regards,
