G'day all,
The pics and articles are from the Avalon Air Pageant in February 1961. Hence the aircraft stuff in the background. The 'Bon Air Scooter' was pretty much thrown together from scrap materials and donated engines; just to see how well it would work, I'd say.
Colin Bonner did build at least one larger hovercraft, the Bon Air 6-1-X - some detail info:

A bit more Trove research found that it came on the market here in January 1960!
