Frozen durians from Thailand have been available in Perth for many years now. Recently my brother in law told me that frozen Malaysian durians are also available now.
The Thai durians sell for about $3 a kilo but the Malaysian ones are $6.70 a kilo. I bought one Malaysian durian to try. Fruit wise there were far less per the durian compared to the Thai ones. Also the fruit from the one I bought was a bit "hard" (Teng Thang in Hokkien.)
