The Great Barrier Reef Marine Park Authority (GBRMPA) takes water quality in the Great Barrier Reef Marine Park very seriously and is planning to review its requirements regarding vessel-based sewage discharge.

It is estimated that total sewage discharge into the Marine Park accounts for three per cent of the entire nutrient load, with tourism vessels contributing a portion of this total.

In light of these considerations, the GBRMPA intends to develop management arrangements that provide for long term protection, ecologically sustainable use, understanding and enjoyment of the Great Barrier Reef for all Australians and the international community.

To achieve this goal the GBRMPA will, through extensive consultation with industry stakeholders:

• Identify gaps and areas of greatest impact through a comprehensive assessment of potential environmental impacts and risks of vessel-based sewage discharge.
• Review existing requirements for vessel-based sewage discharge - both commercial and recreational.
• Examine practical and feasible alternatives such as options to reduce sewage discharge, new holding tank standards and prohibition of discharge of untreated sewage in sensitive areas of the Marine Park.
• Strategies to increase the availability and use of vessel sewage pump-out facilities in marinas and ports along the Great Barrier Reef coastline.
• Consider 'phase-in' approaches where new requirements and standards apply to newly constructed vessels first.
