ABF is working with Queensland police and Comcare to investigate the death on board an ABF Cutter, Commissioner Michael Outram said on Wednesday.

"My immediate concern is for the welfare of our officer's family and of the crew of the vessel. Ongoing welfare support is being provided to them and I have ensured that all ABF officers are offered support at this time," he said.

"To ensure we respect the privacy of the officer's family, the ABF will not be releasing any further information regarding the officer's personal or service details."

The death is now the subject of a coronial investigation.
