Biofouling Management Options
The new Australian biofouling management options for yachts entering Australia will commence from 17 June 2026. From this date you will get to choose to manage your biofouling using one of three options. Vessel owners who meet at least one of the options are less likely to experience the inconvenience of vessel intervention and inspection.
These options are:
- Option 1: Implement an effective biofouling management plan and record book
- Option 2: Clean all biofouling prior to arrival in Australian territory
- Option 3: Alternative biofouling management method approved by the department

Operators of all non-commercial vessels¹ subject to biosecurity control must provide information relating to biofouling management through the mandatory pre-arrival report (PAR). The PAR responses help Australia manage biosecurity risks associated with biofouling on non-commercial vessels.
Biosecurity officers may check this information during a vessel inspection. Relevant documentary evidence must be available if asked for by officials.
Non-commercial vessel operators who cannot demonstrate accepted biofouling management practices will be asked additional questions about how the vessel’s biofouling has been managed. Biosecurity officers will assess the biosecurity risk associated with biofouling on the vessel and may take necessary actions to address unacceptable risk.
The Department of Agriculture, Fisheries and Forestry have updated their website with all the necessary information. Here you can find the Australian biofouling management requirements for non-commercial vessels document that outlines each option.

¹ A non-commercial vessel is a vessel that is used, or is intended to be used, wholly for recreational purposes – for example, a yacht – whether or not crew are employed on the vessel.
