Fireworks confirmed as boat grounded on way to flare report

UPDATE: A flare sighting that grounded the Volunteer Marine Rescue's boat has been determined as a fake.

Hervey Bay Water Police said it was later discovered to actually be fireworks.

EARLIER: Hervey Bay Marine Rescue's primary search vessel and its crew were thrown onto rocks in the middle of a thunderstorm on Wednesday night.

Responding to reports of a flare sighting off Round Island, VMR dispatched Hervey Bay RSL Rescue about 9.30pm on Wednesday night, their main search and rescue boat.

VMR vice-commodore Jill Barclay said the crew battled rough seas, strong winds and lighting in their frantic search mission for the flare's origin.

She said the wind coupled with a freak wave threw the boat onto rocks.

"We grounded it on Round Island and we had an outgoing tide," she said.

"There was no way we would get it off so we had to wait until the high tide at 9.45am today (Thursday)."

The boat was retrieved this morning and now needs two new propellers for their twin-250hp outboards.

The extent of damage to the fibreglass hull is now being assessed.

No vessel in distress was located by VMR.
