Whakakiia te rerenga e whai ake nei: He kaihauturu kaha a Turnbull i te pakanga kaore i angitu
1999 referendum to establish an Australian republic, serving as Chairman of the Yes Committee. Ko ia te tumuaki o te Komiti Ae. I whakaputaina e ia he pukapuka mo te pakanga, ko te taitara "Fighting for the Republic". I te hinganga o te pōti, ka whakapae ia i te Pirimia o nāianei, me te rangatira o John Howard, i te "whakamate i te ngakau o te iwi". I reti a Turnbull mai i te Huringa Reipa o Ahitereiria i te tau 2000, i muri i tana wehenga atu i te poari o Ausflag i te tau 1994; i uru atu ia ki te Australian National Flag Association i te tau 2004.
