There is a company here in Australia that makes what is called a semi-kit of the Armidale class patrol boat.
The company is called APS models and they make a 1:72 model of the Armidale. The kit contains the hull. deck, partial superstructure, gun, mast, fittings and such.
It s called semi-kit as the builder has to make some of the pieces themselves, it is not an Airfix kit, it is much tougher as it is designed for operation out on the water.
APS makes a big range of models in 1:72 scale, all of which are designed to have radio control gear fitted, everything from tugs and patrol boats to frigates, destroyers, cruisers, merchant ships, etc. The modern RAN gets a good look in with the FFG, Anzac, Huon, Fremantle, Armidale and AWD hulls available, plus older ships such as the DDGs, the various DEs, Darings, Battles, Tribals, N and Q class and so on.

If you would like to follow up, send me a message and I will post his contact details, as I don't know the Defence Talk mods thoughts are on what could be seen as blatant advertising
