Under the Australian Biofouling Management Requirements for Commercial Vessels (ABFMR-CV), all foreign-flagged vessels entering Australian waters must carry two documents: a Biofouling Management Plan (BMP) and a Biofouling Record Book (BRB). DAFF biosecurity officers can request both at any port of entry.

Biofouling Management Plan (BMP)

A vessel-specific document covering anti-fouling coating details, in-water cleaning history, and niche area management — sea chests, bow thruster tunnels, rudder gaps, and shaft brackets. It must also define crew responsibilities and procedures for responding when biofouling exceeds acceptable levels. A generic or vessel-class BMP is not accepted.

Biofouling Record Book (BRB)

An ongoing log where every hull inspection and underwater cleaning event is recorded — date, location, method (diver-assisted or ROV), areas covered, Biofouling Risk Level (BRL) assigned, and service provider details. Underwater photo and video records must be attached to each entry as evidence.

Niche Areas: The Most Commonly Failed Inspection Points

Niche areas are recessed or internal hull surfaces that anti-fouling paint cannot fully protect and that standard hull cleaning often misses. DAFF inspectors specifically target these zones because they harbour the highest-risk biofouling. The most commonly failed areas are:

• Sea chests: internal grating surfaces accumulate heavy shellfish and algae growth that is invisible from outside the hull
• Bow thruster tunnels: sheltered geometry allows barnacles and mussels to establish quickly, even on recently cleaned vessels
• Rudder gaps and pintles: narrow clearances trap soft and hard fouling that brushcart equipment cannot reach
• Shaft brackets and rope guards: frequently overlooked during routine cleaning and rarely documented in the BRB
• Dry dock blocks and keel areas: contact points from the last dry dock that may carry live organisms

Each of these must be individually cleaned, inspected, and documented with photographic evidence before arrival in Australia.
