The CA-5, CA-7, CA-8 and CA-9 models were all broadly similar to the CA-3; only the CA-16 variant featured substantial design changes; amongst other purposes, several wing modifications had been made to allow for the carriage of a heavier bomb load, along with the addition of dive brakes for dive-bombing. Sets of 'dive bomber' wings (as fitted to the CA-16) were built under the designation of CA-10A (the CA-10 model was a proposed dive-bomber variant that remained unbuilt), and retrofitted to CA-3s, −5s, −7s and −9s; 113 Wirraways were converted. Seventeen Wirraways were modified post-war and delivered to the Royal Australian Navy (RAN), the modifications were incorporated under the CAC designation CA-20. These 17 aircraft included a CA-1, a CA-5 and numbers of all subsequent variants; they were operated under their original RAAF serials. Production of the type continued even after the end of the Second World War. In July 1946, CA-16 A20-757, the last aircraft to be built of a total of 755 Wirraways, was delivered to the RAAF.
