On Wednesday 13 March, we were down from the Minotaur and, hanging on a bush, were a pair of sunglasses in a soft drawstring case. Nothing special (not prescription glasses, I think) but, if they are yours, let me know.
A couple of days before we'd found a folding carbon-fibre walking pole on the track to Gould Plateau. On return, checking at Lake St Clair Parks Office, they had a report of it being lost & a contact number - so a happy result.
Lesson is - if it's outside your pack, clip it on !
