Three young children have been taken to hospital after powerful winds lifted a jumping castle into the air in Sydney’s inner south, as wild weather caused widespread power outages in the city’s west and left more than 90,000 households without electricity.
Ausgrid confirmed about 40,000 customers had been left in the dark, as swaths of Sydney’s west suffered outages after high winds damaged one of the company’s substations. Another 50,000 customers on Endeavour Energy’s network were also without power.

The outages came after a cool change ripped through NSW, with gusts of wind surpassing 80km/h recorded at Sydney Airport late on Saturday afternoon. The temperature in Sydney had hovered about 30 degrees, accompanied by strong north-westerly winds.
The Bureau of Meteorology has issued a severe weather warning for damaging winds, with peak gusts of up to 100km/h expected across parts of the state.
Emergency services were called to Gardiner Park in Banksia, about 12 kilometres south of the CBD, about 1.20pm on Saturday after the jumping castle became airborne, a NSW Ambulance spokeswoman said. The children were taken to Sydney Children’s Hospital after being treated by paramedics at the scene.
A preschool-aged boy and girl suffered head injuries, while a baby was treated for minor injuries. A woman was also taken to hospital with minor injuries, the spokeswoman said. All three children were in a stable condition.
This was the second incident involving an airborne jumping castle recorded in a matter of hours on Saturday. Two children were injured at a party near Geelong in Victoria in the morning. Both children were taken to hospital with injuries to their upper bodies and were in a stable condition.
Greater Western Sydney and the Blue Mountains were the areas worst hit by the wild winds.
“There’s currently over 250 fault sites. Crews are currently working to make damaged areas safe before restoration work can commence,” an Endeavour Energy spokeswoman said. The company’s website estimated that power would not be restored until the early hours of Sunday morning.
In a statement, an Ausgrid spokeswoman said most customers were expected to have their power restored by 7pm with the remainder by 11pm.
“There are currently approximately 40,000 customers without power after strong winds moved through Sydney and the Central Coast this afternoon,” she said.
“Hardest-hit areas include Bankstown, Milperra and Revesby where high winds have caused some damage to one of our substations.”
Outages were being experienced right across Sydney, including in Mosman, St Ives, Bellevue Hill, Rosebery and Summer Hill.
