Australia produces approximately 2500 tonnes annually, less than 1% of world production.
Queensland is the major producing state.
Production also occurs in coastal NSW, the Goulburn and Murray valleys in Vic and SA and south east WA.
Original (astringent) persimmon has been grown for decades in Australia most commonly as a decorative tree in home gardens. If eaten firm it will 'suck your mouth dry' with the astringency. It is not a pleasant experience and for those who eat it incorrectly and it is a major turn off for persimmon consumption. They must be left till mushy soft before consuming.
Commercial production now confined to regions around Sydney, ie: along the Nepean River with a lot of the production going into the farmers markets in Sydney.
Sweet persimmon (Non astringent) introduced to Australia in late 1970's now equates for greater than 90% of production. It can be eaten firm or left till mushy soft like the original persimmon.
Seasonality:
Persimmons are in season from late February to mid June (Autumn - Winter).
