This is a protective covering produced by the nymphs (larval stage) of
froghoppers (family Cercopidae) - related to aphids, scale insects etc.
The nymphs are called spittle bugs, you can probably guess why. I think the
foam is also sometimes called cuckoo-spit, as well as frogspit as mentioned by
Martin.

Subject: Foam on wattles
Anyone know what this foam is - what produces it? I've seen it on wattles in a
couple of places recently. This photo was taken yesterday in the gardens around
Parliament House - there were quite a number of these bits of foam on several
wattles - and I noticed the same foam a couple of days previously on some
wattles growing beside the Sutton Road off ramp from the Federal Highway.
