Jane, I find that if I stand on my left foot (right foot in Southern Hemisphere) with some tin foil (not aluminum) on my head it helps. Honest! I wouldn't fool you.
Also I sometimes chant the following mantra while focusing on a star, " I wish I may, I wish I might, have some luck on WizIQ tonight!
Let me know how it works in Australia. I have no data to prove my techniques ;-)
George, the village idiot.
PS Both of the above should also work, but it will not be as much fun.
