Power was cut to more than 27,000 homes and businesses in far north Queensland as the mop up from Cyclone Ita continued on Sunday.

Five hundred Ergon Energy staff are working to return electricity to the affected area, which stretches from Cooktown to Townsville.

The town of Ingham has been split in half by flood waters and is isolated, after a night of heavy rain caused roads to be blocked. There was also about $1 million of damage a banana plantation in the indigenous community of Hope Vale, north of Cooktown.

The Bruce Highway was blocked off about 70 kilometres north of Townsville and remains closed until further notice.

Townsville Airport, which shut its doors at 6.30am, will re-open at 5pm with a limited schedule of flights. Passengers have been advised to contact their airline directly to check flight statuses.

Cairns Airport resumed international arrivals on Sunday morning, while large crowds piled into the domestic departures terminal.

Energy Minister Mark McArdle said "everything that can be done is being done" to restore power.

"I would appeal to people to be patient," he said.

"Providing electricity to essential services such as hospitals, nursing homes and water pumping stations must come first."

Mr McArdle said Ergon crews were scheduled to fly to Cooktown on Sunday, weather permitting, where they would work to restore power to residents of Cooktown, Hope Vale and Wujal Wujal, who have been without power for two nights.

By 12.30pm Sunday, 177mm of rain had fallen at Townsville Airport as category 1 Cyclone Ita passed through the region. Two hours later the storm was 60 kilometres southeast of Ayr.

The Bureau of Meteorology predicted heavy rainfall and possible flash flooding, along a 450-kilometre stretch on the east tropical coast, from Rollingstone to Mackay.

Queensland Fire and Emergency Services northern regional director Wayne Coutts said residents in affected areas should shelter at home until the cyclone passed.

"Keep up to date with the movement and severity of the cyclone by listening to your local radio and watching the BoM website," Mr Coutts said.

There were about 130 calls to the SES in the 24 hours to 8am Sunday, with reports of roof damage, flooding and fallen trees coming from Cooktown, Cairns, Kuranda, Mossman and Trinity Beach.

By 1pm Sunday, Telstra reported 1780 landlines had been disconnected, while 3G, 2G and ADSL services were also being affected in some areas.

The clean-up is continuing in Cooktown, where Ita crossed the coast on Friday night and roared through at 230km/h.

While there didn't appear to be widespread damage to properties, some buildings lost their roofs and hundreds of trees were blown over.

"It's just going to be windy, dreary and all that sort of thing today for us - just everybody out there cleaning, getting stuff off the roads," local supermarket manager Richard Szczerba said on Saturday.

The water supply in Cooktown is critically low and will run out of water by Sunday afternoon if locals ignore strict restrictions.

The Cook Shire Council warns that police are patrolling the town and if people are found hosing off their properties they will be fined.

Queensland premier Campbell Newman, who toured Hope Vale and Cooktown today, said there had been no deaths as a result of Cyclone Ita, but urged people in cyclone-affected to avoid non-essential travel.

"Let's not see this turn into an absolute tragedy with someone dying from trying to go through a creek crossing and being swept away," he said.

"That is a real threat today and over the next few days."

On Saturday, the state government appointed Queensland police Inspector Kevin Guteridge as the cyclone recovery chief, the man who headed up the Cyclone Oswald recovery in Bundaberg last year.
