Australians have thanked the Queen for their long weekend with a poll showing support for the monarchy is at a 25-year high.
According to the Roy Morgan poll conducted during the regent's Diamond Jubilee celebration, 58 per cent of Australians support the monarchy, a six per cent increase compared to October.
Support for a republic slid two points to 35 per cent.
Tasmanian Liberal senator and avowed monarchist Eric Abetz said the week of celebrations had confirmed Australians' affection for their sovereign.
"This shows that Australians understand the value of stability of the monarchy as a unifying institution,'' Senator Abetz said.
