The birds love them too hat is why Queensland is so full of prickly pear.
Just around the corner outside an old abandoned fruitbarn there is a variety with yellow fruit.

There are many cactii with edible fruit, dragon fruit being one example.
Around Wowan in Central Qld there is a round cactus beside the road that tastes quite sweet and fruity also.

I live in the desert and I've eaten those since I was a kid, they're very good.

I Love that taste!
