While America might have the Espionage Act, we have an law (passed a year or two ago) that gives mandatory minimum sentences of >15 years for revealing information about ASIO. And sharing the information (even if it's public) carries the same penalty -- so re-tweeting such revelations is a criminal offense. As is viewing it.

Chilling effect? More like dipped-in-liquid-nitrogen effect.

I hope Australia will have its own Edward Snowden, but the immediate repercussions would be far more severe in Australia.
