Soap box/Fruit box

OK, I gotta say something about this, only because it has to do with food justice. Here, I've noticed backpackers complaining about the prices for fruits and veg. I have, however, noticed how almost their entire fruit and veg supply is from Australia. Certainly, they are blessed by having such climates and growing areas that they can grow everything that we can in North America, but also can grow tropical vegetation as well. This allows them to be able to be almost entirely self-sufficient in growing their own food supply; that is very cool.
However, with that comes the fact that they then have to pay the 'real' prices for produce, as they have to pay Australian wages for Australian goods. For example, bananas sell for about $4/kg regularly. However, during their growing season, terrible hurricanes hit the banana growing regions of Australia, and, for a while, bananas cost about $15/kg, as that was the true market cost for bananas. Apples are about $5-6/kg, lettuce is about $2-3 a head, etc...
I have got to say: at least this is food justice, in terms of paying close to the true price for foodstuffs. It then alarms me, that if Australians are paying this much for local foods, then how do we justify paying the Venezuelans less than $0.39/lb for bananas?
