The signing of the Convention for the Conservation of Southern Bluefin
Tuna by Australia, New Zealand and Japan in May 1993 represents an im
portant milestone in the development of management arrangements in the
southern bluefin tuna (SBT) fishery. This convention has emerged from
a voluntary management arrangement regulating catch of SBT between th
e three signatories. This paper provides an analysis of the SBT Conven
tion and details elements of the Australia-Japan relationship which ha
ve been crucial in the development of this international convention. A
lthough signed by the three countries the SBT convention is open to ot
her parties, with the original signatories keen to encourage all State
s engaged in the fishery to join and thus help ensure effective and su
stainable management of SBT into the future. The SBT Convention reflec
ts increased concern over the management of highly migratory species a
nd indicates increased commitment from Japan to join management arrang
ements concerned with these species.
