The first of the new BT23 series of cars to appear, the Brabham BT23A was built with a 2.5-litre Repco V8 engine for Jack Brabham to race in the 1967 Tasman series.

The BT23A was not ready in time for the New Zealand GP in January 1967, but made its first appearance at Wigram, where Jack Brabham set fastest lap of the race after a long pit stop to remedy overheating problems. He skipped the Teretonga race and returned to Australia to try to get the BT23A sorted out, but it was still overheating at Lakeside. After enlarging the nose area on the car, Brabham had a good run to finish second. The overheating issue was replaced by a fuel injection problem in the Australian GP, and Brabham finished off the pace in fourth place. The car finally ran properly at Sandown and Brabham took pole position, finally getting the better of Jim Clark’s Lotus 33 and Jackie Stewart’s BRM P261. The Australian was able to hold off Stewart for the lead until the Repco’s ignition broke and put him out of the running. With the BT23A now fully sorted, Brabham took pole position at Longford and dominated the race: leading every lap, setting the fastest lap of the race, and winning by nearly a minute from Clark. As the BT23A was acting as the prototype for Brabham’s BT24 F1 design, the team’s chances of retaining the World Championship looked strong.

After the Tasman series, the BT23A was sold to Scuderia Veloce for the 1967 Australian Gold Star series.

Built for Jack Brabham to use in the 1967 Tasman series and fitted with a 2.5-litre Repco V8. Won at Longford in March. Sold to David McKay's Scuderia Veloce and entered for Greg Cusack to drive in the 1967 Australian Gold Star and the 1968 Tasman, but Cusack was injured when he crashed at Longford in March 1968, and decided to retire. The car was extensively damaged, but was repaired and Phil West took over the drive for the 1968 Gold Star, starting with victory at Bathurst on Easter Monday. Then sold to Brian Page and used in Gold Star and regional events. Mentioned again in 1972 when Monarch-Ford racer Alan Stewart was said to have it for ANF2. Crashed at some point and the rear of the chassis replaced. Acquired by Peter Simms (Kurrajong, NSW Australia) in January 1980, restored and raced for the first time at Amaroo in August 1984. Raced in Australian historics by Simms for many years. In December 2017, the car was acquired from Simms by The National Museum of Australia (Canberra), and placed on display in the museum.

Driven by: Jack Brabham, Greg Cusack, Phil West and Brian Page. First race: Lady Wigram Trophy, 21 Jan 1967. Total of 24 recorded races.
