Griffo - er, No
Sir Denis James "Jim" Killen AC, KCMG was the member for Moreton (Qld); he was never a senator.
I don't think Killen had much to do with the F111 purchases, as this was signed off under H2; although he did have a fair bit to do with the F/A18s (minister for Defence).
(I am definitely showing my age, and yep, I did vote for Jim)
