Yes. it would. If you can get ot established it will happily sit there through a long hot summer. As for irrigation and water requirements, it really depends whether your talking flood or spray. Flood uses around 1 megaliter per acre per watering. 2 watering 2 weeks apart per cut is required. As for spray, that also depends. I might use 8 laps of a pivot over a cut and that uses roughly 32 megs for 65ac. All depends on in crop rainfall as well. Trouble you will have is without irrigation during your dry season you will be trying to make hay during your wet season. Not ideal for curing as you will need 4 to 5 days after cutting. And that's without humidity. Watering in your dry season will give you the best opportunity to make good hay without weather damage.

Won't grow without it. But yes, too much and hot temperatures will lead to scalding or cooking the plants, particularly if the water ponds on the paddock for too long. I try to avoid watering in temperatures above 36°c with flood irrigation. Spray, can be more forgiving as you are not pending so much water during irrigation. You want to avoid watering if rain is due as well. Good drainage is imperative if you intend to irrigate.

Alfalfa or LUCERNE as the rest of the world know it, grows from tropical Queensland to Tasmania here in Australia (Think from top to bottom of the country). Tassie might only get a couple of cuts whereas Queensland can see up to 11 cuts per year. That said, I find it enjoys a spell mid season to get good yields.
