More than 30,000 lightning strikes battered the Hunter Region as intense 'super-cell' storms hit the east coast overnight.
The storms brought wind gusts of up to 90km/h and golf ball-sized hailstones to parts of New South Wales' north coast and Queensland's south-east.
In NSW, the SES attended about 250 calls for help while in Queensland emergency workers were called to 46 incidents, mainly around Toowoomba, a spokesman said.
Five centimetre hailstones were see in Gresford in the Hunter Valley, while residents in Newcastle also reported a deluge.
The showers have continued on-and-off since, with commuters being warned to watch for possible flash flooding in the CBD.
Meanwhile, the Gosford to Newcastle train line is experiencing significant delays as a result of power lines that are down. Bus service is replacing trains.
