Hi Rod
I am a big fan of the CSIRO website and came across this - while researching Radio Astronomy. The HSC topic that I am working on at the moment is "The World Communicates" which covers waves, sound, light etc.... So to add to my understanding and provide direction for uni in 2011, I decided to apply.

I am booked and paid - just deciding on accommodation.
It would be great to see you there.
Cheers Petra d.
