Up to one thousand people have joined an anti-Adani rally in Sydney's west as part of a convoy travelling north to protest against the proposed Queensland coalmine.
The convoy, spearheaded by veteran conservationist Bob Brown, includes electric vehicles and 180 cars which stopped in Parramatta in Sydney's west on Saturday as part of its two-week campaign up Australia's east coast.
The Parramatta rally was attended by up to one thousand people ahead of the convoy's journey north to Coffs Harbour.
Mr Brown said the campaign had received a huge amount of support since it departed Tasmania on Wednesday.
The Greens party founder hopes the convoy will turn the upcoming federal election into a referendum on the Carmichael coalmine.
"People can decide whether they vote for Adani or for a renewable, clean future," Mr Brown told AAP on Saturday.
"It's a test whether humans can use their God given brains to move to renewables."
The former Greens leader believes the climate will feature heavily on voters' minds when they head to the polls on May 18 given there's been a rise of interest in the issue.
"It's a resurgence that I haven't seen since the 80s," he said.
He insists people are appalled at the lack of action on climate change and urged voters to consider the future of the planet for next generations.
Further protests will be held in Coffs Harbour, Brisbane and Hervey Bay as the convoy heads north to Queensland's Galilee Basin where the proposed coalmine would be located.
More than 800 people have signed up to join parts of the journey which will travel to Canberra on May 5 for a climate rally ahead of the election.
