Australia cyclones cause 'complete and utter devastation'

Two tropical cyclones have slammed into Australia, knocking out power, damaging homes and forcing evacuations in coastal areas.

Tropical Cyclone Marcia hit the Queensland coast between Yeppoon and St Lawrence on Friday morning local time.

Arriving with little warning as a Category Five storm, it has now been downgraded to a Two but still threatens high tides and heavy rain.

Queensland Premier Annastacia Palaszczuk described the storm damage as "complete and utter devastation".
