Bonza was discovered as a chance seedling growing near Batlow, in the Snowy Mountains region of New South Wales. Unusually for an Australian apple, Bonza is a high-chill variety - perhaps reflecting its place of origin.
It is now grown on a small scale in the Batlow area. This area receives high rainfall (50" a year) which makes scab a problem but Bonza has natural resistance.
It is a good pollinator for Delicious and Red Delicious.
