Wild scenes as dozens of anti-coal protestors are arrested, shutting down a Newcastle shipping port

More than 100 climate protesters have been arrested after they allegedly disobeying police orders while temporarily shut down a major shipping channel in Newcastle.

The demonstration, organised by activism group Rising Tide, was held at the city’s harbour this weekend.

Police say on Sunday, a large group of people entered a shipping channel and interfered with the movement of vessels.

The Port Authority of NSW has now suspended all shipping.

According to police, 138 people were arrested after refusing to comply with a direction to move away from the channel.

The group, which has organised the large multi-day protest, claimed a coal ship being forced to stay at the dock was a win.

Police say they have ‘a zero-tolerance approach to actions which threaten public safety and the safe passage of vessels’.

A Port Authority of NSW spokesman said all shipping had been suspended.

‘In consultation with NSW Police and stakeholders a risk-based decision has been made to temporarily pause shipping,’ the spokesman said.

‘The protest activity has compromised the safety of the shipping channel and led to an unacceptable potential risk to public safety, the port and the environment.’

Images show about 150 people waving anti-coal signs, wearing bright colours paddling into the channel in kayaks.

Officers on inflatable police boats and on jet skis were seen dragging protesters into the police vessel.

Laws in NSW make it illegal to obstruct the safe passage of a vessel.

Police are requesting no one else to block the shipping channel.

‘Unlawful activity may result in fines or imprisonment,’ police say in a statement.

‘The NSW Police Force will adopt a zero-tolerance approach to actions which threaten public safety and the safe passage of vessels.’

A spokeswoman for protest organisers Rising Tide said in a video demonstrators were jubilant about disrupting ships.

‘We have blockaded the world’s largest coal port,’ said the spokeswoman, named as Alexa in the caption.

‘Mood here on the beach is just amazing. Everyone is so pumped, so excited, and so hopeful.’

The attempt to block the ship was part of a 10-day ‘protestival’ being hosted by climate activist group Rising Tide, which has seen thousands of people descend on the world’s largest coal port.

Midnight Oil frontman and former Labor MP Peter Garrett performed at the protest with his bandmate guitarist Martin Rotsey.

‘Is the real threat to the Hunter region a group of citizens exercising their democratic rights, or in continuing to export the materials that will burn the world up in a furnace?’ Garrett said.

Last year more than 100 people were arrested at the event, which organisers said was the largest civil disobedience for climate justice in Australia’s history.

Earlier this month, NSW Police launched proceedings in the NSW Supreme Court to have the protest deemed unauthorised on safety grounds.

Justice Desmond Fagan found in favour of the NSW Police and prohibited the planned protests on land and on the water.

But Rising Tide said they retained the right to peaceful assembly.

Maritime NSW attempted to create an exclusion zone around the Newcastle Harbour but that decision was set aside following a successful Supreme Court challenge by Rising Tide.

City of Newcastle Lord Mayor Dr Ross Kerridge released a statement earlier this month providing support for the event to go ahead at Camp Shortland, provided event organisers told people to stay of out of the shipping channel.
