Here's the Australian infrastructure that is listed as critical to US national security:
"Australia: Southern Cross undersea cable landing, Brookvale, Australia Southern Cross undersea cable landing, Sydney, Australia Manganese -- battery grade, natural; battery grade, synthetic; chemical grade; ferro; metallurgical grade Nickel Mines Maybe Faulding Mulgrave Victoria, Australia: Manufacturing facility for Midazolam injection. Mayne Pharma (fill/finish), Melbourne, Australia: Sole suppliers of Crotalid Polyvalent Antivenin (CroFab)."
Maybe if you worked at the Crotalid plant making rattlesnake antivenin and you might like to know that you were a possible terrorist target due to your role in safeguarding the US.
Crikey's ‘Critical infrastructure’ = hysterical reaction had more on this, including
In the event al-Qaeda wants to prosecute a death-by-rattlesnake strategy in the United States, yes, it could take out Mayne Pharma’s Melbourne plant, in the hope of increasing the number of deaths from snake bite, although most rattlesnake bites are not lethal. Or … maybe that would just increase sales of the other, Mexican-developed antivenin Antivipmyn, which some practitioners regard as cheaper and more effective than Crofab.
Or they could sever the Southern Cross fibre optic cable in Sydney (“Australian link broken — rest of world isolated!”). But then, terrorists would know about that from Wikipedia, rather than WikiLeaks. Or perhaps they’d find out from the website of the cable owner.
In fact if you want the exact spot for that cable, consult ACMA’s handy “Sydney Submarine Protection Zones”, which details the precise location of these important pieces of communication infrastructure.

Or if you worked at a nickel mine somewhere.
How critical are these, exactly - I'm not sure.
