GOANA world-class
My wife & I (Americans) thouroughly enjoyed our GOANA trip around NSW in early 2000. We intended to do a Queensland tour; but before we could return, the regs put them out of business.
They ran a world-class operation from my perspective as a customer. I have never flown a C172 that performed like the one I flew for 10 days downunder! I can believe 40,000 injury-free flying hours. We had one lady who was stung by a scorpion at Broken Hill. Curlyw has it right -- the people as well as the equipment were tops. What a way to see Australia!!!
Curlyw is right about Africa too. One of the parties that flew with us in 2000 did an air safari in Africa, and we're looking into it.
