Tens of thousands of Australian students skipped school on Friday to demand politicians take action on climate change.
In Sydney, Town Hall square was packed with students of all ages.
There are a — and I can’t stress this enough — lot of students here at the Sydney #ClimateStrike and they are making heaps of noise as the rally gets underway.
They were calling on the government to take immediate action to halt climate change.
Olis, Catriona, Audrey and Ollie, all 17, told BuzzFeed News they just want the government to "do something".
Some of protesters were very young — like Vincent, who is four months old.

His dad told BuzzFeed News it was Vincent's first rally, but probably not his last.
Others were no longer at school, but wanted to support the students.
They made signs.
Some of them, like 15-year-old Eleanor, also went to the last climate strike in November.
The Melbourne strike also drew thousands of students.

Bella and Calum, both 16, told BuzzFeed News they wanted the government to stop the Adani coal mine, stop building coal mines, and switch to all renewables by 2030.
Mai, 17, said her teachers — especially science teachers — were supportive of her attending the rally.
Simrin and Loren said it was their "duty" to go out and fight for change.
Some of the signs were frankly terrifying.
There were also rallies in Adelaide...
and Brisbane...
...and dozens of other places throughout Australia.
