A google-search brought up this photo of Beaufort T9540:
http://www.edcoatescollection.com/ac...rt%20T9540.jpg
It is in RAF style tail-code, not in the RAAF A9-xxx style.
The LIFE Magazine photographer, Carl Mydans (who took colour photos of RAF Blenheim IVs at Singapore and b/w photos of Brewster Buffalos, Wirraways, Hudsons) may have also photographed the arrival of the Beauforts. Unfortunately, the LIFE mag photo collection is no longer searchable in a user-friendly manner. If you're lucky, you might hit the right combination of search words to yield a worthwhile result.
Good luck,
