There are calls for the removal of shark nets at Australian beaches after a whale calf became entangled in one on Queensland's Sunshine Coast.
The mother and lifeguards attempted to help the baby at Noosa on Tuesday morning but it managed to free itself before Department of Fisheries staff arrived.
NSW Greens MP and marine spokesman Justin Field said the incident showed there was an urgent need for nets to be removed.
"Shark nets are an outdated technology that provides a false sense of security and takes an unacceptable toll on marine life," he said in a statement.
Mr Field said nets were a "political fix" only.
But Fisheries' shark control program manager Jeff Krause said human safety came first and the Queensland government was committed to keeping the nets.
"The equipment remains in place throughout the year as sharks are active along the Queensland coastline year round, and Queensland's beaches are also a regular, popular destination for swimmers even during winter," he told AAP in a statement.
"While shark control equipment does not provide an impenetrable barrier between swimmers and sharks, it is effective in reducing the overall number of sharks in the area, making it a safer place to swim."
