Unfortunately the archive mentioned in the previous post doesn't have anything before 2011 so this radio piece doesn't appear to be available.
Unless I'm mistaken Bill's plane can be seen in the retrospective programme about Alan Whicker which has been shown in the UK. One of the segments in one episode - which covers Whicker's extensive career in television travel journalism - shows him being taken out to one of the NW Tasmanian islands (Trefoil? Three Hummocks?) where a couple were living in splendid isolation which relied to a great extent on resupply by air. It's even possible that this series appears somewhere on YouTube.
In response to one of the previous posts, as one of the people operating a self-funding mining operation at Balfour in the 70s, I'd like to point out that the attribution "alternative" to our small group there is somewhat, if not entirely, misleading. We weren't a bunch of indolent hippies; our existence was totally reliant on our capacity to extract Cassiterite ore - rather than growing turnips or raising goats. This entailed the construction and maintenance of a separation plant involving heavy equipment on a steep hillside - dangerous conditions.
It also required us to maintain ourselves in a primitive camp located in a clearing in a rain-forest throughout the year - generating our own electricity and water supplies etc. We were frequently working unbroken 30 day stretches in gruelling conditions, particularly in winter - the west coast gets about 80"of rain p.a. Access in and out was extremely difficult and apart from food supplies we needed large quantities of fuel. It would have been wonderful to have the use of the sort of equipment shown in programs such as "Gold Rush". Even a D7 was out of the question. We hauled in a generating plant and the associated cable, motors etc - about a 7 ton load - on one of the old Studebakers (nominal capacity 2.5 tons). The rivets were popping out of the chassis like bullets.
Bill Vincent was absolutely vital to our capacity to keep the operation going, as I've mentioned previously, as were many of the people of Circular Head. Communication was only possible because we were given a VHF radio associated with a small logging operation. This enabled us to get a message out which had then to be relayed to various suppliers, not to mention Bill. During the mutton-bird season he'd often buzz us and drop a couple of boxes of birds off, gratis, at our strip and at other times simply buzz the hill where we were working and throw a couple of rolled and tied up newspapers out of the window of the plane. What a terrific bloke he was.
