A guy by the name of Glenville Pike wrote a book about the Cape York mail runs, "WINGS OVER THE CAPE - The word's Longest Mail Runs"
Wasn't a bad read, although maybe a little contempory now. Not sure if it is still about, but the ISBN number is (was?) 1-875375-07-4
I'd say that there are many other great CYA mail runs stories that should have been published ....(and then again perhaps some not!!).
Have to say though, that the CYA FNQ postie job was one great job.
BTW, gidday to "Caravan Dan"
