Just before the South Australian border, we cooked up our remaining vegetables (onions, celery and garlic) and mixed some with tinned tuna for lunch. We did this because it is forbidden to take fruit and vegetables into the area to prevent the spread of bugs such as fruit fly. Cooked veg and juiced fruit are legal. We stocked up again in Naracoorte before travelling to the Caves where we are camped.
We had time to check out huge diprotodon, constrictor snakes, and other reconstructed ancient critters at the Wonambi Fossil Centre then to visit the vast Wet Cave and finally to walk past Western Grey kangaroos on the World Heritage hike before settling in for the night.
