More than 6000 homes and businesses remain without power in the far north as Cyclone Ita begins to move away from the Queensland coast.

Ergon Energy has restored power to about 20,000 properties since noon on Sunday, although Premier Campbell Newman said the worst-hit areas could go weeks without electricity.

On Monday morning, Energy Minister Mark McArdle said vegetation damage and issues with access had made it difficult to restore power to parts of Kuranda and the Cairns northern beaches.

There were also 736 properties in Townsville that were waiting to be re-connected and 1100 customers offline in the Mackay, Whitsunday and Proserpine regions.
