What is the weather in Melbourne and Sydney like at the end of July?

Sydney can get some lovely weather then . It wont be hot but should be nice enough to have a good look around. Melbourne is touch and go. Could be bitterly Cold it's a risk at that time of year. The Gold Coast today is beautiful. The Marathon is on at the moment and the sun is out People swim in the beach all year around. If you want really warm weather then go to the tropics it is the dry season now Cairns will be nice or the Whitsunday islands should be glorious as well. There are often cheap flights from Sydney or Brisbane with Jetstar or Virgin blue.
