Sorry, that's bollocks. In my past life, weirdly, I was responsible for a weather-derivatives business for a bank who's footprint included Australia. Large deals, complex risk..........and lots of data. Australia is pretty much the gold-standard for accurate weather data going back to early Victorian days. It's extremely robust. We crunched the shit out of it, and I can tell you with certainty that eastern Australia is getting hotter and drier. Whether that's the result of anthropogenic climate change is a different question.
And when was this? The data you would have used is now being changed. I guess all the rain we've been getting isn't real. Funny thing in Australia, we have droughts and then it rains, a lot. If the historic data proves that warming is getting worse, why are the alarmists changing it? Hint, they need to change it to suit their religious zealotry.
ETA: Fix a typo.
