Almost $92 million has been unveiled for reef management, taking the total pledged by the federal government to protect the world-famous drawcard to almost $4 billion since 2014.
The lifeline has been announced as Australia sweats on UNESCO's draft verdict on the reef's health in coming weeks, hoping to avoid the "in danger" tag that would prove damaging to tourism.
The Climate Council has welcomed the latest funding but warned the money would barely make a splash without steep cuts to emissions.
"The Great Barrier Reef needs all the love we can give it after being hit by eight mass bleaching events since 1998, so funding is obviously welcome," chief executive Amanda McKenzie told AAP.
"But without serious cuts to climate pollution, this money is like trying to put out a bushfire with a water pistol."
She said the Albanese government had approved 36 new and expanded fossil fuel projects that would fuel the marine heatwaves threatening the reef.
Home to dazzling coral and marine life, the reef underpins about 77,000 jobs but is under intense pressure from climate change, polluted runoff and repeated mass bleaching.
The May budget has allocated $91.8 million for projects to improve water quality, ramp up monitoring and trial coral‑spawning techniques designed to help damaged reefs recover more quickly after bleaching events.
Environment Minister Murray Watt said the package, which included $56.9 million for implementing the Reef 2050 Plan and $34.9 million for the Great Barrier Reef Marine Park Authority, was about giving the reef a fighting chance.
The World Heritage Committee is set to meet in July, when UNESCO could again push to list the site as "in danger".
An official black mark would be a global embarrassment and a serious blow for reef tourism operators who depend on international visitors chasing a bucket‑list experience.
Senator Watt conceded the threat was concerning but insisted an "in danger" tag would not save a single coral.
"What it would do is deal a very damaging blow to our tourism industry internationally," he said.
Queensland Environment and Tourism Minister Andrew Powell said the state was working with Canberra on reef protection and had "already seen progress".
It coincides with claims coral is being chipped off the reef for the wild live‑export trade supplying private aquariums.
At a protest in Sydney on Thursday, the Australian Marine Conservation Society alleged harvesters were taking up to 190 tonnes of coral a year from the reef.
