The Bureau of Meterology (BoM) says the Gold Coast has copped the brunt of Queensland's mass downpour, as severe storms continue to ravage the state.
The once-in-a-century weather emergency gripping both Queensland and New South Wales has affected 10 million people across eastern Australia.
More than 200mm of rain drenched the Gold Coast in just a few hours overnight, with "intense flash flooding" soaking the region.

"The hardest hit region was regions around the Gold Coast, where we have seen up to 213mm fall in a short amount of time," BoM forecaster Jackson Brown told Today.
"Keep in mind that, that was a similar amount that was recorded on the day previous. Some fairly intense flash flooding occurring through there."
A flood watch remains in place for southern parts of Queensland, from the South Australia border to the South East Coast.

SES Queensland state coordinator Brian Cox said the emergency service has been inundated with calls for assistance as severe storms continue to cause chaos.
The state has received nearly 820 requests for assistance since the storm began, as well as a couple hundred from overnight.
"The rain has really impacted everywhere from Moreton Bay, all the way down to the border," Mr Cox told Today.

"There has been a range of calls for assistance from flood inundation to homes, to support for people that have got leaky roofs, all the way to trees down as well as a landslide in the Hinterland area."
More rain is expected to bucket down over the next 24 hours, with the state on high alert and all SES crews on standby.
"It is quite widespread, like NSW, we have got a widespread area that is going to have more inundation today," Mr Cox said.
"We put all our crews on standby. The regions in Brisbane, south-east and even south-west are on the highest readiness of alert for our teams."
