Coastal evidence
A few posters have mentioned the possibility of some items of wreckage washing up on West Australian beaches.
We have some very isolated areas where debris items could remain undiscovered for long periods of time before anyone ventured there. It would depend entirely where the items were carried to, but we can only hope that if this does turn out to be the case, something lands in a more populated area where people frequent the coastline on a regular basis. This is a very big state with a small population.
