Ahhh, yes he did ! - I’ve read “The Hazelton Story” by Denis Gregory. It took him 6 days walk to get to the Coxs River post office- a remarkable story. The poor old Auster was a wreck, but he still managed to sell it for 300 quid !
Nowadays there a couple of golf courses if you follow the Great Western Hwy to Blackheath. I’m not sure about tennis courts though.
Sadly my days of flying PIC over the mountains are no more, so I guess my job is to look for those tennis courts now.
