After a number of very hot days, it’s been good to stay in places with pools. Tonight we are at Mataranka in the Northern Territory, camping near the natural hot water swimming hole called Bitter Springs. Attempts at underwater photography varied in quality. Himself, pictured below, is very able to swim deep enough for a passable image to be taken. Myself, not pictured here, had to hang on for dear life to a submerged tree trunk to stay down long enough, resembling a goggle-clad squirrel with nut-filled cheeks as I held my breath.
