YEPPOON Coast Guard Deputy Flotilla Commander Paul Florian was waiting on the shores of Rosslyn Bay Harbour for shark attack victim Allan Countryman.
Volunteer coastguards of vessel RMH Rescue brought Mr Countryman safely back to shore on Saturday after it answered the calls for help.
Vessel RMH Rescue was in a training drill nearby when the call came from Miall Island.
The volunteer crew jumped into action and were on the scene within minutes.
Mr Florian said there were four volunteers on the vessel.
"If the RMH Rescue wasn't out there training it would have meant a time delay, the situation is all very lucky," he said.
"The people on the vessel conducted themselves well, they all felt that it was fantastic to be able to help someone in need."
Mr Florian said he had never seen anything like the incident before.
He and was glad the volunteers were in such close range at the time of the attack.
"The coast guard crew don't train in shark bites, they train in boat-handling skills and being able to get there," he said.
