Having arrived at the South Australia/Northern Territory border, we handed over our paperwork (COVID-19 arrangements) and were free to go through, but not stay at this beautiful, free campsite. The officer suggested Kulgera, down the road about 20km.
We had been here before for fuel, but had not experienced its hospitality. There is a reasonable store on site, an art gallery that showcased local work and a pub.
Famous (?) for the big 4X can, it also had its own travellers ‘artwork’/ collection – of sandshoes in this case.

Good, clean amenities and plenty of room, with drive-through sites.
