@Miss Rosie do you know where he actually lives? Maybe you could go on a road trip to see if he’s ok and bring us news? I’m not sure how far away you are from him but I think you’re the closest!
Wait for the summer and you'll probably see him on here https://www.perisher.com.au/reports-cams/cams#Xv8 when the snow comes.
Perhaps he’s Broken down somewhere Just waiting for a recovery truck That could take awhile in the outback
I have his address, but don't really know him that well .... not that any of us really do I suppose ... so if a mod could perhaps make contact.....it's been a long time !
