A frantic cry for help from fisherman Maike Hohnen "Coastguard Mooloolaba, Coastguard Mooloolaba" was heard over the radio call to the Coastguard before the search and rescue mission unfolded.

They were the last words heard over the radio from the missing trio.

Their vessel sunk soon after.

Debris including an esky and fuel can was discovered and heard over the radio.

"We got the call first up and basically alerted water police straight away," flotilla commander Rod Ashlin said.

"It was actually found by another boat, not the search party who were a lot further north.

"This would never have happened if we didn't have a radio operator on shift but we have one 24/7, 365 days a year."
