Picked up a map/brochure the other day "Flinders Ranges, Eyre Peninsula, Outback South Australia - 4WD Tracks & Repeater Towers".
It's got a good size map showing all the repeater towers, PAR's, and 4WD tracks in those areas....also information on 4WD self drive treks etc. A lot of the self drive treks I have never even heard of, I didn't realise there were that many in the Flinders.
It can also be downloaded (5mb) from:
South Australia - 4WD brochure
The paper version has a much clearer map than the PDF version tho.
Hope the info is useful to somebody
Cheers
