Parts of Australia’s third-most populous city Brisbane were underwater Monday after heavy rain brought record flooding to some east coast areas and killed seven people.

The flooding in Brisbane and its surrounds is the worst since 2011 when the city of 2.6 million people was inundated by what was described as a once-in-a-century event.

A 59-year-old man drowned in Brisbane’s north on Sunday afternoon after he tried to cross a flooded creek on foot and was pinned against a fence, Queensland state police said on Monday.

Queensland emergency services warned life-threatening flash flooding was occurring south of Brisbane in parts of Gold Coast city.

Residents were advised to shelter where they were unless it is unsafe to do so. Access to many areas was cut in multiple places, Queensland Fire and Emergency Services said in an alert.

Emergency crews made more than 130 swift-water rescues in 24 hours, officials said.

All seven flood deaths have been in Queensland state, of which Brisbane is the capital. A search continues for a solo sailor, aged in his 70s, who fell overboard from his vessel in the Brisbane River near the city center on Saturday.

Police were also searching for a man missing from Goodna, west of Brisbane, and another Esk, northwest of Brisbane.

South of the Queensland border, police on Monday were searching for a man after officers heard him calling for help on Sunday in floodwaters in the New South Wales town of Lismore.

Multiple emergency flood alerts were in place for Brisbane suburbs, where 2,145 homes and 2,356 businesses were submerged or would become so Monday as the waters rose. Another 10,827 properties will be partially flooded above the floorboards.

The Brisbane River peaked on Monday at 3.85 meters (12 foot, 3 inches), officials said.

That was 61 centimeters (2 feet) below the 4.46 meter (14 foot, 3 inch) flood level reached in 2011, officials said.

WINTER STORM TO HIT NORTHEAST WITH HEAVY SNOW, RAIN

Queensland Premier Annastacia Palaszczuk said the rainfall over Brisbane had been extraordinary since November when authorities were considering water use restrictions due to a shortage.

"It is still a significant event, and I think everyone would agree no one has seen this amount of rain in such a short period of time," in the southeastern area, Palaszczuk said.

Brisbane Lord Mayor Adrian Schrinner said the floods are "very different" to 2011 because the rain pummeled the region for five days. In 2011, the rain had stopped days before the Brisbane River peaked and authorities had warned for several days of flooding downstream.

Queensland Transport Minister Mark Bailey said major roads had been cut. Train and ferry services across Brisbane have been halted, he said.

"We’re going to have localized flooding in a lot of areas for a couple of days yet," Bailey said.

South of the Queensland border, the New South Wales town of Lismore was bracing for its worst flooding on record.
