MARPOL is under continual review at the marine environment protection committee of the IMO, and amendments are adopted as considered necessary. The convention was modified by the protocol of 1997, whereby a sixth annex was added, relating to the prevention of air pollution from ships. The miscellaneous provisions Bill amends the 1991 Act to enable the necessary regulations to be made in that respect. I look forward to discussing the miscellaneous provisions Bill with Senators in due course.
