I am going to expand on the excellent information above to say that the only places it really snows are in the snowy mountains and parts of tasmania. Other parts of southern Australia may get a day or 2 of snow but it is never heavy and ends up as just a lot of slush. You could never build a snowman out of it or anything. Winter over here is basically just rain and cold. It can get around zero degrees Celsius at night but is usually warmer than that during the day.

Also that video is a pretty accurate depiction of an aussie soap. No lies.
