Mackay grandfather, Greg Trembath, is launching a campaign to stop a Mackay Harbour Sand quarry.

He says he is fighting to shut down a sand mine off Mackay beach to protect the environment for future generations.

He has launched his Line in the Sand campaign to bring the area under conservation status as the land falls under Mackay strategic Port Land territory.

The North Queensland Bulk Ports Corporation’s Land Use Plan states fauna surveys recorded 26 species of “special conservation status” on port lands.
