sydney, melbourne, cairns

thinking of going to sydney, cairns, melbourne from march 25 - april 6 this year. is the weather likely warm (75F) for the beaches? how unpredictable is temp in cairns? love the ocean/great barrier reef. worry that the storms will continue until the time i travel and we'll be stuck in hotel not being able to do anything.

You are still on the Pacific Islands site. The Australia one is one above it.

sydney and melbourne will probably reach a maximum of about 75F in march - april
melbourne weather is pretty fickle, so expect it to be cold one minute then hot the next.
