Hi Hodgies!
Good on you for making the trek. There is plenty of fuel all along the Plenty and it does vary in price. You should try living out here

! If we have to get a fuel truck off-schedule they charge us over two bucks a litre... goodness knows what this new budget will do to little bush fuel stations.
There is 'plenty' to see on the 'Plenty' if you'll pardon the pun! If you come past Gemtree on a Wednesday or Saturday night we do the free history show, that fills you in on the pastoral history of the area. Areyonga (who commented below) will be able to fill you in as he has been a couple of times now!
https://www.facebook.com/pages/Gemtree/121877771172739There is also now Tower Rock which is just off the Plenty Highway, on the northern section of the Binns Track. It is a land form very like the Devil's Marbles - minus all the backpackers if you know what I mean. That is a newly excised piece of land that has been made a Conservation Reserve, named after my grandparents (Mac and Rose Chalmers). As far as I know you can free camp there. If you do, the grave is there... tell Nanna & Grandpa I said hello xo.
Not far from Tower Rock is the Box Hole Meteorite Crater. We can give you free mud maps if you call in at Gemtree, to show you how to get directly there without annoying any pastoralists!
So good luck on your adventures, travel safely, and if you can manage to pull up at our place on a Wed or Sat I think you will find it just magic. We have a deal for forum members to stay 2 nights and get 1 free. Not sure what your schedule is like.
Cheers!
Kate
