Yes, and the current prohibition on the sale and possession of Caulerpa under the Fisheries Management Act 1994 will continue under the new Biosecurity Act 2015.
Yes. The full prohibition on sale and possession of Caulerpa will continue to apply anywhere in NSW and fines will apply. Heavy fines will also apply for the reckless or intentional spread of Caulerpa.
Waterway users should thoroughly wash down and check equipment for Caulerpa after use. Caulerpa can remain viable out of the water for days in the right conditions. Collect and dispose of any fragments in a plastic bag into general waste. Never return any Caulerpa fragments to the water.
Waterway users should not disturb any populations of Caulerpa as this can cause fragments to be dispersed to other areas where it can settle and establish new populations.
No. The only control method thought to be effective for removing Caulerpa is applying extremely large volumes of pool salt. However, this will not guarantee complete eradication and is not considered feasible in many circumstances.
This method also requires a permit, which includes comprehensive environmental assessment. If approved, the work may only occur with direct DPI involvement.
There is no guarantee that Caulerpa will not reoccur in an estuary afterwards due to fragmentation, or in undetected populations of Caulerpa within that same waterbody.
Caulerpa is not considered as severe as once thought following 15 years of scientific observations and published research into the impacts of Caulerpa on native seagrasses in NSW:
Yes. Passive surveillance through community, stakeholder and research projects will continue.
No. Active monitoring of Caulerpa has ceased. DPI will continue to investigate reports of Caulerpa infestations in waterways where it has not previously been found.
You can help us by sharing advisory information with your friends, colleagues or fellow stakeholders to raise awareness about the importance of cleaning boats and equipment before moving to other waterways. Reports of suspected new detections in new locations can be made to DPI Aquatic Biosecurity.
Please report new detections of suspected Caulerpa to DPI Aquatic Biosecurity on the 24 hour telephone reporting hotline (02) 4916 3877 or via email to firstname.lastname@example.org
DPI will investigate new reports of Caulerpain waterways where it has not previously been known to occur, to confirm and quantify the incursion, and to inform potential communication activities. Control efforts are unlikely to be supported due to the challenges of successfully eradicating Caulerpa.
Please report all illegal activity to NSW DPI on 1800 043 536.
