You guys don't get any frost or snow? What are your winter low temps. Happy New Years also.
For where I currently live
Gold Coast weather
For where Gas roughly lives
Brisbane weather
For where chilliover roughly lives
Sydney Weather
For where JR roughly lives
Melbourne weather
As you can see (keep in mind Australian/New Zealand winter is from June to August) the Gold coast and Brisbane are pretty warm year round
Sydney less so and Melbourne can get some pretty cold days
As for frosts/snow in the cities at least it is not really heard of in Brisbane/Gold Coast (not proper frosts as I used to know in New Zealand anyway where everything was frozen solid).
You would have to ask the other locals on here about there particular areas as I am not sure about some of the country/suburbs surrounding the cities.
