In 1986 Lady (Anita) Smith, widow of Sir Keith Smith, bequeathed her entire estate to the establishment of the Sir Ross & Sir Keith Smith Fund and directed that the income of the Fund be applied in perpetuity for "advancement in the State of South Australia of the science of aeronautics and of education therein".
The famous flight started in Hounslow, England on 12 November 1919 and ended 28 days later on 10 December 1919, when they landed at a makeshift airstrip near Fannie Bay Gaol.
The Sir Ross and Sir Keith Smith Fund commemorates the achievements of two distinguished South Australian pioneer aviators - Captain Sir Ross Smith K.B.E., M.C., D.F.C., A.F.C., and his brother Lieutenant Sir Keith Smith K.B.E.
