Thanks so much for the feedback so far. Seems there is opportunity to turn it into a DONEx. Need to find some time later today to work on the puzzle. Continents are part of the DGLOB, but it does not seem to count Asia as part of the route to Australia, contrary to the DONEx
Realised so far this RTW solution has plenty of opportunity, but somehow it makes you greedy as well as you would like to squeeze in more and more
