In 4 years of pelagics and other seabird surveys off Port Stephens (and 2 off
Swansea) that I have been running / involved in, we have only recorded SGP on
one trip (Sept 2012, when we had 2 birds). Mind you, we've only had NGP 5 or 6
times. Any seawatched GP's that I have been able to confirm to species level
off Nobby's have all been Northerns too.
I'm sure the SGP's were the more commonly encountered of the two when the trips
were being run by Baxter/Hansbro (from about 2000-2006?) but I don't have that
info in front of me.
Also, if you checked the SOSSA Monthly Guide before it was given a welcome
refreshing recently you would have seen that SGP's were more commonly recorded
off W'gong up to 1999. The guide shows a different story now though (see link
below, which uses data collected between 2000-2013).
