Lots of things on this thread I didn't know. But I do know how to answer the question, so I will. Now.
ERSA. List of aerodromes. FAC section for that aerodrome. "Aerodrome & Approach Lighting".
Example, Dubbo, page FAC-D-2. 90m spacing. (This hyperlink probably won't work after 22 August 2012.)
I don't concern myself with if-it's-this-sort-of-runway-then-this-otherwise-that-unless-it's-a-Tuesday-then-the-other-thing kind of reasoning. There are so many exceptions, exemptions, grandfather rights and so on that the only way to know is to look it up, for that particular runway.
Cheers,
