Demolition of a derelict house

A derelict house just below us on the hillside is finally being torn down. This is probably due to local government saying "clean that up before cyclone season or we'll do it for you and charge you a lot of money". Scientists are predicting an "active" cyclone season for Queensland, so there is a lot of pressure on the half-completed construction projects to clean up anything that can blow around -- before they close up for the 2- to 4-week summer break. And of course pressure on householders with junk in their yards. Removing the roof began 10 days ago. Using a chainsaw to cut the roof battens. No use of any of the required safety equipment is evident. Smashing down the weakened structure. Some cleanup of debris still to go, and some stubborn structure to knock down.
