Passage Rocks is a few hundred metres from the Middle Island Green Zone and should be included as a part of that zone for the following reasons:

Passage Rocks (Keppel Bay, QLD, Australia) has the 2nd highest coral diversity of the whole Keppel group (Jones et al. 2011).

Passage rocks reef is incredibly diverse despite only being 4.5 Ha. The site of the highest diversity, (Humpy island), is 68 Ha (and is on the opposite side of the island). Therefore it would seem that the Passage Rocks is very significant.

Passage rocks is a refugia for coral species not well represented in other parts of the Keppels - important given the stress to corals from flood plumes and agricultural runoff via the Fitzroy river and proposed Development.

A 250 berth marina development is proposed adjacent to Passage Rocks and the dredging & extra boat traffic required for the marina could harm the fragile ecosystem.
