I agree, Gympie was not built with flood mitigation in mind.

Like a lot of gold mining towns, Gympie evolved around the mines themselves, with little thought for the future. We still get the occasional collapse of an ancient mine shaft, resulting in a sink hole. I think the last one appeared in the middle of a road. This has happened in peoples backyards too. All the current rain may contribute to future sink holes.
