Did mango harvest a few years back. In the shed - I packed, himself sorted. Not hard to pick up. Not really hard work, though involves standing. Pay was ok.

Since mango season starts soon in NT and Kununurra, and is later in Qld, you can follow the mangoes from about Sept to Xmas or later. People with fork lift tickets are often in demand in harvest work.
