Cyclone Owen will "wreak havoc" across Queensland, with remote communities braced for 280km/h winds and much of the state on flood alert, the premier has said.

Annastacia Palaszczuk said the state had done all it can to be ready for Owen, which is expected to hit as a severe category-four storm late on Friday or early on Saturday.
