In 1921 the Qantas fleet consisted of two biplanes - an Avro 504K with a 100 horsepower (74 kw) water-cooled Sunbeam Dyak engine and a Royal Aircraft Factory BE2E with a 90 horsepower (67 kw) air-cooled engine. The BE2E was purchased for £450 ($900) from Charles Knight, a Longreach stock and station agent who, having experienced a turbulent delivery trip, swore nothing would induce him to fly again.
