This was a major prolonged event. Had it hit a major city, all bloody hell would've broke loose. Hogan Island is less than 200km SE of Melbourne btw.
Not 30 hours. But it's pretty obvious you've never been in a large cyclone. Yasi didn't pass in a few hours....more like 14 hours or so. And that was only the destructive core. But we had gale force winds for a lot longer. Not only that, but the peak winds were stronger here, and a lot stronger only a little further north.

You mightn't realise this, but for every 1mph over 100mph in wind speed, the pressure exerted by that wind doubles. 169km/hr winds are strong, but winds of 180km/hr (which we got here) are 12 times as strong. Our house was vibrating in the gusts of wind and the power lines that remained up, when you could hear them, were "singing"...making a humming sound.

However, Hogan Island did take a battering.
