Following its tour in the Mediterranean, No. 78 Wing was reorganised at Williamtown. On 16 March 1955, the wing headquarters was re-formed, and Nos. 76 and 378 Squadrons were disbanded. No. 75 Squadron remained with the wing, augmented on 21 March by Nos. 3 and 77 Squadrons. On 1 April, No. 478 Squadron absorbed the maintenance functions of No. 77 Squadron. Nos. 75 and 77 Squadrons initially operated Meteors from Williamtown and No. 3 Squadron was based at RAAF Station Canberra, where it flew P-51D Mustangs. By November 1956 the wing had re-equipped with CAC Sabres and all of its units were stationed at Williamtown.
