Home owners have spent the night cleaning up after thunderstorms brought torrential rain that flooded houses in Melbourne's outer northern suburbs.
The State Emergency Service (SES) dealt with 130 calls for help from the Sunbury, South Morang and Mernda areas where flash flooding damaged properties.
The internal ceiling of a supermarket caved in in Sunbury, where there was a big hail storm.
Flights were delayed at Melbourne Airport.
Kim Shackleton says a gush of water rushed through her house in Plenty Road in South Morang within minutes.
"The kitchen's flooded, the lounge room's flooded, my beautiful Balinese garden's flooded," she said.
"It's all flooded. I feel like I'm in Bali right now."
Anthony Grovic says he had to sandbag his house in South Morang.
"I went upstairs and had a look off the balcony and I could see the water coming from across the road," he said.
"It went straight across the property and it started coming into the house.
"I had about four-and-a-half feet of water in the courtyard at one stage. I had about three or four inches in the house."
