Willis Island observations: http://www.bom.gov.au/products/IDQ60801/IDQ60801.94299.shtml
Willis is a flat little Island with a manned Met station about 450 km off the FNQ coast, set up as a cyclone advance warning point in 1926 - well before satellite and weather radar gave us the ability to see "out there." It has taken a more-or-less direct hit. The anemometer crapped out at 8:37 am about one hour before the cyclone centre with the last recorded maximum wind gust at 185 km/h. The station stopped sending data at 10 am. The minimum pressure of 938 hPa is very low indicating an extreme cyclone.
I guess they would have got the station crew out. Even though it has a cyclone bunker I wouldn't want to try it. The island has a max height of 9 metres so it wouldn't be obvious what was land and what was sea. At these wind speeds you don't get conventional waves, the waves get torn apart to produce a layer of driving air and water mix that one of my oceanography lecturers described as "too thin to swim in, too thick to breathe."
