Fruits trees and shrubs that thrive in pots

Griff starts with ...
Hi all,

I have a courtyard in Brisbane that I want to fill with potted plants, preferably fruit trees and shrubs. I'm new to the gardening scene, so I'm hoping someone can tell me what kind of fruit trees/shrubs will thrive over a long period in pots. The courtyard is sheltered from strong wind and receives at least four or five hours sunlight most days. It's an area where i want to sit and relax, so reasonably attractive plants would be nice, particularly ones that don't require a trellis. They don't all have to be fruit trees either, nice bird-attracting plants or impressive flowering plants would be nice too. I understand potted plants require a lot more care and attention than their regular ground-dwelling cousins, but I'm not looking for anything that requires intensive maintenance or tricky irrigation set-ups.

Any advice and tips would be greatly appreciated.

Thanks
