Hi Les,
I have a passing interest in twitching (origin UK) or birding.
I have been up to O'Rilleys several times. Its a Rainforest retreat. Problem is that over the past 20 years it has become very commercialised and the birds have moved out. Still there are a few around but not anywhere near as it used to be.
Also I live on acreage North of Brisbane. We have our own little rainforest here. There are many species that visit. Including Chanel Billed Cuckoos.
They are very shy but they like the rainforest every summer.
Work takes up too much of my time and so I am not into any active birding these days.
Cheers
