Which are the most prestigious views in Australia? A panorama of Sydney Harbour, with the Opera House and Harbour Bridge? The Melbourne city skyline which has to have some of the most impressive highrise in the world right now?
Or would that be a vista that includes the internationally beloved Melbourne Cricket Ground or an outlook over our iconic Bondi Beach?
"I think looking at the harbour with the Opera House and bridge would have to be the best," says McGrath agent David Howe in Sydney. "We know some people who buy multi-million dollar homes with such views just so they can visit once a year to watch the fireworks! It's incredible." 
In Melbourne, Marshall White agent Marcus Chiminello believes wonderful views over the city, MCG and Domain are the most highly prized. "To live in the epicentre of Melbourne, being able to see all the icons ??? It doesn't get any better."
It's hard to put a value on views, but undoubtedly certain sights add an absolute premium. A good view can add anything from 10 to 15 per cent to the price of a property, says Chris Curtis of buyers agents Curtis Associates, but a very special one can add as much as 25 per cent.
"Having both the Harbour Bridge and the Opera House will add the highest dollar value," he says. "And for my money, the bridge is more valuable because of its symmetry, all the activity on and below it, and the way it spans both sides of the harbour."
The Manhattan-style Melbourne skyline is a stunner, and has the benefit of being interesting by both day and by night, while a beach view has the downside that, in the dark, it disappears.
"It's also about how easily you can see the view from the home," says Egan National Valuers senior valuer Kris Cviker. "Is it there if you look up from the sofa, or is it only there if stand in a certain position?"        
Of course, there are few homes overlooking other sights consistently voted among Australia's top10, such as Uluru, the Great Barrier Reef and Port Arthur.
Some homes with top views are similarly unlikely ever to come up for sale; the prime minister's official residence Kirribilli House, for instance, with its stunning harbour views, and massive grounds.
"If that ever sold, it could make a new record price in Australia," says Howe. "It could be over $50 million, or a lot higher ??? It's hard to say. But it has what has to be the best position on the harbour in the whole of Australia."
