AN advertisement featuring wildlife warrior Bob Irwin encouraging Queenslanders to fight to protect the Great Barrier Reef will air in Brisbane during Wednesday night's State of Origin coverage.

The ad explains what conservationists see as the dangers the reef and its marine life face from rapid port development, dredging and dumping along the coast.

It has previously aired in regional Queensland.

"Our reef is one of the greatest wonders of the world and I'm not about to let it be ruined in my lifetime," Mr Irwin said.

"With the increased traffic of these huge gas and coal ships coming through the reef, the threat is very real indeed.

"At the end of the day, the Great Barrier Reef doesn't belong to the Queensland Government and it doesn't belong to the Australian Government. It belongs to every single Australian and every person around the world."
