Sky News host Rowan Dean says Greens Leader Adam Bandt decided to go out and “protest against fossil fuels”.
Hundreds of protesters decided to block the shipping channel at the Port of Newcastle.
The protestors used kayaks and floats to cover the waterway.
Mr Dean said Adam Bandt is an “idiot as well as a hypocrite”.
“Seriously try and make your kayak out of basket-weaving sustainable grasses or whatever, Adam, and see how far you get.”
