I've gotten myself a basic model of it,

the shorter bit on the right is going to be under the house. That is where I plan to put some of the nest boxes, and the third closest to that is colour-bond, and that's where there are going to be alot of perches so that the birds can easily get out of the wind and/or rain. The bit on the left without the wall is the only bit that will get sun in the winter (all of it will get it in the Summer). So that's also going to be mostly clear of bushes and the like, so that in winter the birds can lay in the sun, and dust-bathe. There is also going to be a path through the middle leading to a bench. I am planning on having it mostly leaf litter on the bottom. Will this be easy enough to clean? Is it just a raking of the top level every week or so, and replenishing it with fresh stuff from the yard? I plan to have the Following species:
Star Finch: A Pair of them
Painted Finch: A Pair of them
Scarlet-chested Parrot: Are these going to destroy the plants and (possibly) chew through finch mesh?
Diamond Dove: Will these be too flighty?
Painted Button-Quail: Are these difficult to get in Sydney? I've heard varying things, but will they be okay in a Planted Aviary, or still too flighty?
Blue-faced Parrot Finch: A Pair.
Are any of these plans bad, and can I do anything better, and do you have any ideas for more?
Thanks!
