Queensland authorities are investigating an alleged illegal fishing incident involving three fishers near the protected wreck of a WWII Catalina flying boat south of Cairns. Reef Authority compliance officers reportedly intercepted a vessel during patrols near the Frankland Islands on August 10 and allegedly found freshly caught fish onboard.

The vessel was reportedly within a protected Maritime Cultural Heritage Special Management Area surrounding the wreck of RAAF Catalina A24-25. The aircraft crashed in 1943, with all 11 crew members losing their lives.

Authorities are reminding people that protected maritime heritage sites have special rules designed to safeguard historic wrecks and surrounding areas. Fishing and other activities may be restricted within designated protection zones.

The alleged incident highlights the role of compliance patrols in protecting underwater cultural heritage and marine environments around Far North Queensland.

The three fishers could face fines of up to $3,600 each if the alleged offences are established. The matter remains subject to the relevant investigation and legal process.
