ENVIRONMENTAL campaigners will blockade Newcastle Harbour today to highlight the contribution Newcastle's coal industry has on climate change.
The flotilla of activists had aimed to stop coal ships entering and leaving, but no ships will be moving from the dock, the Newcastle Port Corporation said.
Green group Rising Tide will blockade the port from 10am to try to stop ships entering or leaving the harbour.
Organisers said they hoped the protest would draw attention to the fact that the coal industry produced about two-thirds of Australia's greenhouse footprint.
But the port corporation confirmed yesterday that all coal shipments from the port had been cancelled.
Rising Tide spokeswoman Carly Phillips said the corporation removed shipping times from its website when a protest was announced and tried to thwart their protests regularly.
"Australians are coming together to occupy the world's biggest coal port and this country's single biggest contribution to climate change," she said.
"People are angry that State and Federal governments are overseeing a massive expansion of coal exports at a time when the industry needs desperately to be phased out."
She said they were expecting hundreds of activists to turn up.
The protest could be a replay of a climate change protest in July last year when more than 1000 protesters descended on the Newcastle coal link.
Police charged 37 people.
Extra police are expected to be on duty around the harbour.
