You want to reach this cache? Have a look at the picture series - you better be like a camel or carry lots of water. Next bore water hole: 36km airline through the desert (and there are not many along the track). Don't be misleaded by the Highway - if you are coming from the east it is quite a rough track, from the west side its "just" heavily corrugated - 489km between the nearest service stations.
The cache itself is not so hard to find. But first you need to get there. Next airport/trainstation: about 900km airline. Next sealed road about 550km. Next international airport: 1200km on the other side.
