I am a little confused, the only drilling in the FI that I know about took place in 1998 by Desire Petroleum, the company who are there now. Which drilling are you referring to in 1982?
The rig was the Diamond M Epoch: it's far too long ago to remember the details told to me, but it was drilling between Argentina and the FI in mid to late 1981. Certainly in disputed territorial waters, and IIRC drilling for either BP or Shell. The Epoch arrived in Australian waters after completing the drill programme and transiting the South Pacific in April 1982.
