>From their report:
A goby we found in a bore drain on Proa station has been preliminarily
identified by the Queensland Museum as the tadpole goby, Chlamydogobius
ranunculus. The fish were highly abundant from 80 to 200 m downstream of
the bore head, then rapidly became less numerous until they were virtually
absent 1 km downstream. Where fish were most abundant, the water
temperature was 30.6 oC, the conductivity was 557 ls/cm, and pH was 8.32.
At the bore head 40 m upstream, the water temperature was 48.1 oC,
conductivity, 568 ls/cm and pH, 7.89. The goby ranged in size from 17 to
46 mm. The smaller sizes were juveniles, so this species was breeding at
this site.

No rainbows. Most of the odd stuff were gobies, but they also got an odd
grunter, catfish, and some new hardyhead records (one which they
identified as C. marianae which is very odd). No one has really had a
good solid look around out there, so it is not too surprising. Was just a
quick and dirty survey for though for the most part.
