If you look at the world, you will find that the most populated parts are between mountain ranges and delta regions. An example would be India.
They get three months of 24/7 rain in the wet season, June to August. Then in November to January they get heavy snow falls in the Himalayas, which thaw in March to May. The peasants figured out thousands of years ago, that you could heavily irrigate all year round.
Australia has no high mountain ranges, which means we just rely on rainfall. If we start heavily irrigating again we will run out of water. People wonder why the First Nation’s people never practised irrigation. Doesn’t take an Einstein to figure this out. So Mr Barnaby, if you want to save your cattle industry, just ban heavy irrigation practices.
