Let us look at the words in the BoM headlines announcing the last twelve three monthly temperature Outlooks.
I count the word ‘warm’ or ‘warmer’ used NINE times, the word ‘cooler’ was used ONCE and ‘mixed’ was used THREE times.
Here is a map for that same twelve month period

The continent has been mainly cooler than average.
The BoM clearly has a bias towards announcing ‘warm’ events.
I rest my case m’lud.
