We feel sorry for the tourists who paid for a holiday at the Gold Coast this year. There have been very few days when there wasn’t rain or a storm.
Yesterday we tried to see the floor under the bath as that is likely to be the same as the subfloor under the tiles. There is an access hole under a veranda beside the bathroom, which allowed the plumber to change our spa pump a couple of years ago. I couldn’t lean in far enough to see the floor. I will need a cheap borescope to see further.
We could see obvious signs of dampness on the brick wall, but this may have been caused by rainwater penetrative the veranda roof. The dark area to the left felt damp, and the salt line points to long-term exposure to water.

We have been packing food, clothes, and travel gear to take out to our caravan to make it ready for our trip to Tamworth. The critters are already sitting on clothes I put out to pack.
