I had the privilege of going on board HMAS Armidale while she was in Cairns, in September 2013. I had built a model of that vessel several years previously, mainly from line drawings and photos, plus some invaluable help from one of the forum members, and used the visit to take photos of the modifications made since I built mine. I was then able to modify my model to better represent the real ship, fortunately those mods were quite easy to make. Unfortunately, HMAS Bundaberg was badly damaged in a fire in a dockyard in Brisbane not long after, so badly in fact that she was scrapped. I now only have the photos, and my model, to remind me of that visit, although there are 13 other Armidale Class boats still active (as far as I know) in the Royal Australian Navy.
