While spending Christmas in Australia is both surreal and wonderful, December weather can be a little unpredictable in Melbourne, so January is prime time to go. There’s also no better antidote to those European winter blues, but if you want to go at the most cost-effective time, go just before the Australian Open starts. In 2015, the second week of January was only $161 AUD, compared to $215 AUD and $217 AUD for the last two weeks respectively and 29% cheaper than Melbourne’s most expensive week all year.
