Support Driver/s needed for Walking Feat

I'm currently support driver for Sarah Eagle of Walking Feat who is walking from Armidale to Melbourne for mental health. We are currently laid up in Merimbula as she recovers from injury and exhaustion having made it as far as Eden on Tuesday. This is Sarah's 2nd big walk this year. Earlier she walked the 1,100km 88 temple pilgrimage in Japan. These walks are also helping to raise funds for SANE Australia.
I need to get back home soon to continue training and preparing for The Happy Walk but we don't have any replacement drivers.
We plan to get back on the road this Tuesday from Eden.
Sarah's walk is scheduled to finish in Melbourne on Sept 10th in an event with Pat McGorry and other mental health representatives but if anyone can help out for just a few days or a week it will be very much appreciated.
Sarah's support vehicle is a converted Merc ambulance/campervan. Automatic, diesel and easy to drive.
If you can help please contact me direct on 0412147355 before the 15th August, please keep in mind phone range will be unreliable for a few days walking south of Eden.

I hope someone here can help out.
Cheers
