Hundreds of people have been rescued, with the navy assisting, after some areas were hit by almost one metre of rain overnight, with more falls to come on Monday.
One of the worst-hit communities is Wujal Wujal, north of Cairns, where nine people including a 7-year-old child and health workers are stranded on a hospital roof.
The Aboriginal community received 260mm of rain overnight but floodwaters are easing, allowing a rescue party to assist the stranded group on Monday.
Hard to capture the volume of water on video but walking in I could feel the ground shaking amidst a deafening roar. An unprecedented 6ft of rain fell on the catchment over the past few days. #cairnsfloodpic.twitter.com/xrR56HaAwm
Much of the Far North is underwater tonight, as a result of the most severe flooding the region has experienced in almost 50 years.

Hundreds of people have been evacuated with HMAS Cairns naval base assisting.
The Australian Defence Force (ADF) will send more troops from Townsville while emergency services will be airlifted to Cairns on Monday.
“We will deliver along with the Queensland Government... whatever is necessary,” Prime Minister Anthony Albanese said of the ADF support.
“The important thing at this point in time is to ensure that people are kept safe,” Albanese said.
“A number of people are isolated and have needed rescuing from their terrible circumstances so our thoughts go to all people in those communities.”

“Some areas have received 1.5 metres to 2 metres of rainfall since we first felt the effects of Tropical Cyclone Jasper,” a Bureau of Meteorology spokesperson told AAP.
Rain is finally set to ease on Monday as the ex-cyclone gradually moves north after hovering on the peninsula since first impacting the Queensland coast mid last week.
“However we do have several hours of heavy rainfall before the system is able to weaken and move away,” the bureau warned.
Hundreds of homes are flooded in Cairns where levels have reached record levels “by a substantial amount”, according to James Cook University geo-hydrologist Professor Jonathan Nott.
Due to large numbers of urgent calls for assistance from the Halloways Beach, Machans Beach and Yorkeys Knob area, we have deployed significant rescue vessels including SES flood boats, QFES rescue boats, QPS water police vessels, surf lifesaving vessels and local vessels.
“The forecast tragically is predicting more rain still throughout today and the major flood warnings are in place for several communities which are already cut off or without power.
“We have activated already financial support for residents directly impacted as well as for local councils to assist in what will be a major clean-up.”
Federal disaster assistance has been extended to more areas to help residents and local councils cover response and reconstruction costs.
