Ha! new gps batteries required James.
Brother Doug of Mendi Motors, Waghi Valley Transport, advised this am that a outer mainplane removed from VH-MAE after the Wapenamunda prang, was transported to and sited at the Wabag Country Club.
The country club was/is sited on the northern side of the runway opposite the old parking bay. So, I assume that your trip down the Baiyer must have included a run through Wap to Wabaga.
Mistery solved. All donations to Sharpies benevolent and aged fund. Hoho.
