I have been to 4 total solar eclipses.
1. Port Moresby, PNG in 1983. It was perfectly clear.
2. Big Island, Hawaii, 1991. It was cloudy.

3. Woomera, SA, 2002. It was perfectly clear, but too short.
4. Side, Turkey, 2006. It was almost perfectly clear and nice and long.
The main thing to look at is the weather prospects. See:

Also be mobile so you can drive to a better location if need be.
I suggest we also have an IIS astrocamp near Cairns before or after the 14/11/2012 eclipse to look at the northern milky way.
