Torrential rains and high tides flooded low-lying towns in the northern parts of New South Wales forcing Australian authorities to issue evacuation orders to residents.
The communities around the Tweed River were evacuated after river water burst its banks on Tuesday.
The gloomy conditions due to the La Niña weather pattern is bringing with it heavy rains, powerful winds disrupting electricity, internet and other utility networks.
On Tuesday, the storm moved south of NSW bringing a threat to floods to the inland.
Rains of about 1,0000 millimeter had already poured in four days, which is somewhat similar to a cyclone.
Emergency Services have warned people to stay indoors and avoid driving through floodwaters.
Some roads in the area between Tweed Heads and Taree were forced to close due to floods.
Officials received over 3,000 calls for emergency assistance.
Luckily there haven’t been reports of deaths or injuries, but authorities said they were investigating a man’s death in a car crash on Queensland’s Sunshine Coast.
Australia’s famous Byron Bay’s Main Beach has disappeared, as extreme weather batters Australia’s east coast, officials say.
The Main Beach is popular among tourists and it had already previously depleted due to erosion.
Simon Richardson, the mayor said “severe weather” and “massive swells” were smashing what was left. “We’re watching our beach disappear,” he said.

La Niña season:
La Niña season is a weather pattern associated with increased rainfall and cloud cover in Australia.
There is a strong correlation between the strength of La Niña and rainfall: The greater the sea surface temperature and Southern Oscillation difference from normal, the larger the rainfall change.
There are also cooler daytime temperatures south of the tropics and fewer extreme highs, and warmer overnight temperatures in the tropics. There is less risk of frost, but increased risk of widespread flooding, tropical cyclones, and the monsoon season starts earlier.
Typically, La Niña sees a 20% increase in average rainfall from December to March in eastern Australia, says the Bureau of Meteorology.
However scientists say that climate change is also intensifying La Niña’s impact, and making weather patterns more erratic.
