In those years c.1966-7, just as I joined the Basic Aircrew Training, some large groups of RAN FAA pilots were trained at NAS Pensacola, with traps on the LEXINGTON with the T-28C, before going to Helo Training and then return to NAS Nowra for Wessex 31 conversion. Later some went to Vietnam via Iroquois training. and then to EMU unit in South Vietnam. It was a time when the RAN FAA was regenerating fixed wing again; but also increasing overall helo numbers for the new role with the new [fixed wing] USN aircraft. After Vietnam service some Iroquois/Wessex pilots, who had trained in USofA, went on to A4G [& S-2E/G] flying. Earlier in the early to mid 1960s the RAN FAA had been winding down - getting rid of fixed wing, to being what it is today - a helo only force. The Oz trained certainly envied the T-28C trained at the time. Later RAN A4G pilots exchanged with VT squadrons along with LSO training etc.
I was a little later in the timeline. I flew the T-34C in the training command, having missed the T-28.
Would have been fun though to fly that big radial engine!
