I suspect that what happens here with cyclones is what happened there (but in reverse)
We get the most severe damage can be up to 100km south of the track of the cyclone as it comes in over the Great Barrier Reef, where the lucky ones are on the north side of the cyclone track
This is because in the southern hemisphere the cyclones rotate clockwise, so anything to the south of the track (of a westbound cyclone, which is the only ones we obviously get in Queenslands East coast) gets fresh winds straight off the ocean and maximum destruction, the people on the northside get the `return' winds from back over the land- which have usually lost most of their moisture and some of their windspeed by then
That's what happens here every year when the cyclones hit us (oh joy) but could be a possible explanation for the differences in damage north and south of the actual storm track (which is usually based on the eye path)
