The thumbnail looks like she is taking a shit next to the tent. Don't do this unless it isn't your tent.

Solid suggestions but missed “lock food in the car or esky” At Mambray creek from our deckchairs, we watched a 1.5m water monitor ransack the campsite opposite us over half an hour. Ate scraps out of their firepit, Managed to get its front half into their food bag hanging on the camp kitchen with its tail whipping around in circles. It even licked a couple of their mugs on the table. The grandad came back and i told him to wash his cups because a goanna had been licking them. He just simpered and avoided my eyes as if i was crazy.
