We're no stranger to floods here in South Coast NSW Australia, but there is absolutely no doubt whatsoever that flood events are becoming 1) more frequent and 2) more extreme. These are, unfortunately, indisputable facts. I always make a point of filming any local extreme weather events, usually with my Mavic 2 Pro drone, because seeing it from the air gives you a far better impression of what the conditions are really like. The East Coast Low that caused this flooding brought over 300mm of rain in a single night and lead to landslides and flooding all the way up the east coast of Australia.
