UPDATE: A juvenile whale has been freed from shark nets off Rainbow Beach on Thursday afternoon by Queensland Boating and Fisheries Patrol's Marine Animal Release Team.
Queensland Shark Control Program manager Jeff Krause said the 5m whale was badly entangled in the net.
"Sea conditions were very good and this enabled the team to cut the ropes off.
"Throughout the release the whale was relatively calm and was near the surface, which meant it could breathe easily."
Anyone who spots a whale or other marine animal tangled in the shark control program equipment should phone the 24-hour Shark Hotline on 1800 806 891.

Queensland shark control program manager Jeff Krause said an adult whale was nearby.
"The Marine Animal Release Team was activated after the entanglement was reported by the government shark contractor this morning," he said.
"The team is on location and undertaking preparations to cut the whale free from the nets.
"Sea conditions are very good for the team to assist in the release of the whale."
This is the eighth whale this migration season to be caught in shark control equipment in Queensland.
