The survey sounds a great idea.

For those outside Sydney's northern suburbs, the Australian Museum &
Birds Australia have an online survey for Superb Fairy Wrens at:

Also there are surveys about first annual  observations of Koels and
Channel-bills and backyard birds.

I don't know about Superb FWs as indicator species though. They can
certainly persist in very heavily modified habitat  This morning I
saw 2 at King Street Wharf (where the cruise ships dock) - in the heart
of Sydney's CBD.  Their density is said to increase with some types of
disturbance so they may be (to some extent) an anti-indicator species.

The density of Superb FWs in Sydney northern suburbs in this map:

is surprisingly low and maybe the Northern Beaches survey will through
some light on this.
