Another convergent boundary exists between the Bird's Head and the Banda Sea Plate to the south.

The Banda Sea occupies the main portion of the Banda Sea Plate.

The Banda Sea Plate is a small tectonic plate underlying the Banda Sea in southeast Asia.

These trenches are the subduction zone of the Indo-Australian plate beneath the Banda Sea Plate, where the Indo-Australian Plate moves northwards.

A small divergent boundary exists along the Sulawesi part of the border with the Banda Sea Plate and transitions into a convergent boundary as it bisects the Banda Sea; the rest of the borders being transform boundaries.
