Thought I remembered one of those in someone's back garden in New South Wales:
"After their use in the Vulcan project, one of the two Avro 707As was provided to the Royal Australian Air Force to conduct aeronautical research. WD280 was transferred from the Royal Air Force in March 1956, and was loaded aboard the brand-new aircraft carrier, HMAS Melbourne, for the voyage to Australia. Arriving in Sydney in May 1956, the 707A was then transferred to HMAS Sydney and shipped to Melbourne to begin test flying at RAAF Base Laverton. Operated by the Aircraft Research and Development Unit (ARDU), WD280 was equipped with recording instrumentation, and was flown in a variety of tests including low-speed airflow separation and handling of the then new delta wing design. The aircraft finished flying with ARDU in 1963, and in 1967 WD280 was sold to Mr Geoffrey Mallett, and was transported to his home in Williamstown where it was a feature of his back garden until being obtained by the RAAF Museum in 1999."
