Well, Venus, I think radio astronomy is where it's at. And Australia has the potential to become the world leader in the field.
Have a look at the SKA website:
www.skatelescope.org and have a read of the SKA location proposals:
http://www.skatelescope.org/pages/p_locations.htm.
Clearly, Australia is where the SKA has got to go, in my unbiased (

) opinion. And if that's not a *positive* for Australian astronomy I don't know what is.
