Oh yes average weather.

I get 78 75, but close. So then let's look at that rainfall.
BoM's rainfall stats are in groups of 23, 25, 25, 30 years.

Average rainfall for those periods are approximately - 28.99, 28.91. 21.51 and 34.56mm.

So the average for the last 30 years is 34.56mm and for the base period 1961-1990 is approximately 24.56mm.

So on average today's climate is wetter than 1961-1990. 

The rainfall is simply too random to really worry about averages. One third of winters receive NO rain.

Oh dear poor Barney, who has never made a mistake. And of course that would be if it was a mistake.

Really? You want to compare one year's data against an average?

You know where the data shows both more and less rainfall.

Let's see By my count 78  75 out of 104 years -  rain. 78 75/104 = 72%. By your count 82/104 = <79%. So "at least 80%" is a lie.

28% of the time it doesn't get winter rain at all. Now I would consider 28% "often". You may not.
