Daybreak today revealed the damage caused when tropical cyclone Steve swept through Cairns last night. Trees and powerlines are down, with around 40,000 homes without power in the city and many roads blocked. Damage to houses and businesses was extensive but generally not major, though several buildings were unroofed and city streets littered with debris. Schools were closed for the day, and the airport and port of Cairns closed until the afternoon. Local flooding also caused problems, though rainfall around Cairns was not as great as expected.

More serious problems were caused by Steve as it crossed the Atherton Tablelands to the west of Cairns. Between 200 and 300mm fell in the area late yesterday and overnight in an area that had already received 200 to 300mm in the previous 2 days, causing the Barron River at Mareeba, the Tablelands main town, to peak at a record 12.4m this morning. The town was isolated for most of the day, and without water until late afternoon when the town's water supply pumps failed. A caravan park and 14 houses were evacuated in the town. Roads leading to the Atherton Tablelands were impassable all day, with the main Gillies Highway, which connects the Tablelands with the coast, expected to be closed for a week due to extensive washaways. South of Cairns, the main Bruce Highway was closed at Gordonvale by the Mulgrave River, while a youth was drowned in a flooded creek near Tully.

Moist northerly air converging into a slow-moving troughline appears to have been responsible for unusually heavy rain in Esperance WA this morning. 70mm fell in the town between midnight and 9am, flooding low-lying areas and up to a dozen houses. An area of The Esplanade had to be closed when drainage failed to cope with the downpour. Widespread blackouts resulted from a high voltage powerline fault. No thunder was reported by the Esperance observer.

Flooding continues to cause problems in other parts of WA, Qld, NSW, SA and NT. In WA's Pilbara, a group of 26 tourists and police had to be airlifted to safety after heavy rain turned creeks south of Karratha into raging torrents over the weekend. In the Qld/NT border country, the Georgina River is still causing traffic disabilities, with people stranded at Avon Downs by metre-deep water over the bridge. In the Territory, the Tanami, Docker River and Sandover Highways are still impassable, but are expected to be opened tomorrow. The repair bill for NT highways has been put at $4m. In far north SA, the Stuart Highway was reopened today, but most other roads remain impassable, and are likely to remain so for another week or more. Airdrops of food and supplies continue, with Uluru (Ayers Rock) still isolated and linked to the outside world only by helicopter. In NW NSW, about 30 properties are receiving food drops, and are likely to be isolated for another 6 to 8 weeks. However, water is expected to cover large areas for up to 6 months, promoting fears of fly-strike among bogged sheep. An estimated 12,000 sheep have been drowned in the NSW floods.
