The coda to the DBR4's racing career came in mid-1960, when a car was shipped to Australia for local racers Lex Davison and Bib Stillwell to compete in the Australian and New Zealand national championship Formula Libre races. Fitted with a 3.0-litre engine the car performed much better than had been the case during its brief Formula One life, and Davison took second place in the 1960 Australian Grand Prix. To reflect the increase in engine capacity this car was officially known as the DBR4/300. Stillwell retained the DBR4/300 until the end of the 1962–63 season.
