Given the location, these might be the same birds that Margaret Leggoe
commented on and sent photos indicating young (1 or 2) hobby/ies.
I have at various times seen somewhat similar interactions between
galahs and hobbies and between galahs and brown goshawks. The motives
for these are curious. I have wondered how well equipped galahs are, to
distinguish between hobbies that are probably not a danger to them and
peregrines that certainly are. Surely brown goshawks are also a danger
to galahs though probably not if they aren't able to sneak upon them. As
for cockatoos they often seem to like making a fuss over various others
species.
As for hobbies and brown goshawks, apart from Black, Whistling &
Brahminy Kites, most Australian raptors are not sociable towards other
raptors of another species.

Sandra, we were at CB about 10am and saw the same behaviour, between
hobbies and cockatoos. Several cockatoos were involved. But before that
we saw a juvenile brown goshawk in foliage in a tree, well hidden. When
it took off, the hobbies were after it in a flash It managed to get
out of harm's way. Then the cockatoos took over, harrassing the
hobbies. Galahs were involved in the action as well. It was all very
interesting, especially as there was not much else to see. We did not
see the wedgetail eagles
Worth an article in Gang Gang?

Interesting interactions at CB today between two hobbies, a sulphur
crested cockatoo and two galahs. The hobbies were chasing the galahs on
and off, and were in turn chased very closely by a single cockatoo. I
watched this going on for about 15 mins, with short breaks as the two
hobbies chased each other. The cockatoo was very persistent, watching
carefully if a hobby landed in thick foliage, landing close by and
walking up the branch till it was close enough to prod the hobby into
flight again, then took off after it. some field guides say hobbies are
known to engage in play flights with other birds - perhaps they were all
just enjoying the beautiful morning! three wedgetailed eagles also
sighted - two overhead and one sitting in a tree near the large pylons.
Two immature Aust grebes on one dam, two immatures and a parent on the
big farm dam.
