I really like my Giottos MTL 9360B tripod legs. I wasn't too happy with their MH5001 Three Way Head, however. I replaced it with a Manfrotto 460MG. As my signature indicates, I only have a G12 so I don't have the weight concerns of a DSLR with a heavy lens setup, so the 460MG is perfect for me. I like being able to adjust one axis at a time, so if I need to adjust just the level or horizontal angle, I can do it independently. If I have all the knobs loosened, I can adjust everything at the same time.
Giottos manufacturers their products in China, I think... so perhaps you could buy from one of their HK distributors. btw, I'm 6'2" and the 9360b is just the right height for me... so if you are going carbon fiber, that would be the 8360, if you want the 4 section legs so the collapsed height is shorter for ease of transport. I prefer the lever locks (MTL), but I see posts both ways here. Some swear by the twist locks. Giottos lever locks are adjustable so if they loosen over time, a simple tightening with an allen wrench will do the trick.
The 8300 and 9300 series have the multi positional center column, a very useful addition for macro shots. Their website does a decent job describing it. Here's a youtube explanation: http://www.youtube.com/watch?v=JNvY8tDT5wQ

I don't know if Amazon ships to Australia or not, but that's where I purchased mine.
