More than 300,000 people have flocked to climate change rallies in 110 towns and cities across Australia, calling for governments and businesses to act immediately. The Global Strike 4 Climate, held across the world on Friday, was the biggest climate mobilisation in Australia's history, with more than double the turnout of the March protest. A whopping 100,000 protesters flooded the streets in Melbourne, while Sydney saw 80,000 people march through the CBD to the Domain. Protesters were demanding a target of net zero carbon emissions by 2030 and a transition to 100 per cent renewable energy.
