Thousands have gathered in Sydney to demand climate change action in the midst of a devastating bushfire season which has destroyed more than 700 homes and seen smoke pollution blanket much of the state.
A sprawling mass of people crowded Town Hall on Wednesday evening, with one police officer at the scene estimating the number of protesters could exceed 7,500.
Some wore the face masks people have donned to cope with the smoke haze, while others brandished signs reading: "Denial is not a policy", "Less debate more climate action", "For my grandkids" and "Climate change is a public health emergency".
Police lined the pavements to stop the crowd spilling onto the road and light rail line, while buses were diverted and delayed by up to 30 minutes.
Marcus James, from Sydney, said climate action was an issue across all sectors of politics and he felt a moral obligation to attend.
He said both major parties needed to do more "and get along just to do more".
"I cared about the issue for quite a while but I think having the bushfires reach Sydney is very, very - I suppose it makes it quite lurid," he told AAP.
"It's right in your face and you're breathing it in.
"I think it highlights that climate change and bushfires and natural disasters around the world but especially in Australia, doesn't discriminate and it sort of affects all sectors of the population."
Elise Vohradsky, from Western Sydney, said she was motivated to attend after seeing smoke shroud the city on Tuesday.
"I went outside and couldn't even see anything, like it was just smog," she told AAP.
"There's so much loss and devastation - and not just the people, the cities but the environment, the animals."
She said she felt "pretty angry about it all" and wanted to do something but didn't know what.
"I guess that's why I was like, well this is on, at least I can turn up and be part of a visual representation of how many people aren't cool with this," she said.
Babette Robertson grew up near Wingham on the mid north coast, which has been impacted by recent bushfires.
She said her family had been spared but their friends had lost homes.
"It's so devastating. I just find myself crying some days ... and dad just sends photos every day and it's just so heartbreaking," she told AAP.
She accused the government of ignoring the science of climate change and said she hoped she would be heard and people's concerns would be acknowledged.
"They don't listen to us," she said.
