In relation to the first part, as you'd be aware, 82.1(d) defines damage to public infrastructure:

(d) the conduct limits or prevents access to it or any part of it by persons who are ordinarily entitled to access it or that part of it;

I think the answer to that would be yes. In relation to the second part of your question, it is in 82.2, public infrastructure; 82.2(e) reads:

(e) any infrastructure, facility, premises, network or electronic system … that:

(i) provides or relates to providing the public with utilities or services … of any kind; and

(ii) is located in Australia; and

(iii) belongs to or is operated by a constitutional corporation or is used to facilitate constitutional trade and commerce.

Obviously, it would depend on a number of circumstances as to whether it fit that definition.
