I was a bit curious also so googled and then rang the breeder of the last pair I bought and yes June starts breeding season .
I thought the same about my Quarrions who prefer to breed in winter also .
I had in the back of my head issues about days being shorter and the cold nights ... anyhoo it is a worry and I would prefer young born in warmer weather but the only way to ensure that would be to remove nest boxes and knowing my luck they would either not breed or my girls would become egg bound .
Bird care say ...Nesting months: August to December
Parrot info say ...Breeding begins in April. (Qld site )
I think they just do want they want
