I'm preparing an oral presentation on whether or not Australia should leave ANZUS, but can't find much information regarding the effect the separation would have on the Five Eyes agreement.

On the Wikipedia page for ANZUS it states:

"The two countries [US and AUS] also operate several joint-defence facilities in Australia, mainly ground stations for spy satellite, and signals intelligence espionage in Southeast and East Asia as part of the ECHELON [aka Five Eyes] network."

Does this imply that Australia's Five Eye's connections are detached from the ANZUS treaty?

On the Wikipedia page for Five Eyes, it says:

"These countries [Aus, Can, US, NZ, UK], with a similar common law legal inheritance, are parties to the multilateral UKUSA Agreement, a treaty for joint cooperation in signals intelligence.

Can it be taken from this that they are totally separate treaties, and as such, are independent?

More generally, if Australia left ANZUS, would its military intelligence suffer in any way?
