Just a small point. It may have been longer to PH but there are other aerodromes enroute. Geraldton would've been equidistant from turnaround as Learmonth. Geraldton is some change under 2000m x 45m (although not ideal it is certainly adequate). Then Gin Gin at 1830m x 45m and Pearce. PIC had other options enroute to PH.
