DHC4 A4-234 walkaround from Avalon 2009. The Caribous are due to be retired from ADF service in 2009 so this airshow was, I believe, their last public performance. Many of the 'Bous are Vietnam Vets and have served Australia for nearly 50 years. I will miss the wonderful growl of it's two P&W engines. What will replace the Caribous has yet to be decided as at May, 2009.
