Thats basically the situation Australia and New Zealand are in now, the Governor General is sent for final approval by the monarch.Its entirely ceremonial and tradition, but you would hardly call Australia and New Zealand in 2013 British. Also is the Dominion of Cairns cannon, it might be better to have it as the Dominion of Townsville. Townsville has both a fairly large army base, a slightly larger population at 196,000 vs Cairn 157,000 and far better agriculture and water security then Cairns. Said agriculture is also food including a lot of potato cattle and horses, vs Cairns who have agricultural land bu less with most of it cash crops like sugar cane or up on the Atherton Tablelands (where again the majority of it is cash crops). the mountain which would have to be navigated to bring that food from the table lands to Cairns would be pretty difficult without trucks and the like.
