John Bunting. In March 1983, the incoming
Hawke government appointed Lawler Ambassador to the Republic of Ireland and
Ambassador to the Holy See, serving until his retirement in 1986. Lawler lobbied to have the post of Ambassador to the Holy See permanently resident in Rome, but this did not occur until
