It is the Australian Woodill Wildfire.
If my English don´t fail It is a Woody Woodill effort to produce an “international car” in Australia in about 1961. He had Bob Gurr design it in metal rather than his earlier fiberglass-bodied cars, it looks that he very nearly entered production with it, but the crash of the Australian stock market that year kept that plan from fruition. Woodill only planned to build the cars in Australia (on Triumph Herald chassis, at that), and then export the cars to the United States, thus the left-hand drive and California license plate. From Hemmings.
