Vanuatu is on top of our list, believe me. My wife wants to visit as many islands as we can get to as she has this idea (not unfounded, I guess) that a lot of the islands may well be under water in the not-too-distant future (I hope I'm not scaring you at all - not my intention) so she would really like to see them.
Get the hell outta here! What a coincidence about your Dad being in my hospital. Its a large complex and I work in the admin. side of things so I doubt I would have seen him. But you never know.
The tower is called the Centrepoint Tower. I've been there once in all the years I've lived here. The Taronga Zoo is one of my most favourite place in the world! I'm such an animal lover, I could spend weeks there and not get sick of it. I agree with your assessment of Kings Cross as well. I have a good friend who lives there and some of the stories he tells me are disturbing.
Same goes for you. If you are ever over here and need a tour guide or a night on the town, just let me know.
Cheers and speak to you soon,
Maso
