    Summary:

    A large anticyclone had moved to the east of Tasmania and a low-pressure system was centered to the west if the Great Australian Bight. This produced a gentle south southeasterly airflow providing a comfortable day and an expectation for plenty of sub-Antarctic seabirds.

    As we left the harbour we could see albatross soaring out to sea but immediately inshore were Little Penguins and a small group of terns, including White-fronted Tern. Soon we were among Black-browed, Campbell, Gibson’s, and Indic Yellow-nosed Albatross. The diversity of seabirds was exciting and we had added Brown Skua, New Zealand Cape Petrel and Southern Giant Petrel to the day list by the time we had cleared Wollongong Reef. The later carried a US band that suggested it originated from the Antarctic Peninsula.

    As we cruised east, we encountered more Brown Skuas, a White-capped Albatross, the first FAIRY PRION of the day and a first year WANDERING ALBATROSS on our way to the edge of the continental shelf.

    Just inside the 200-fathom line, we ran into some good water with surprising numbers of FAIRY PRIONS in evidence and the first pterodromae of the day so we set up a drift-and–berley session. This turned out to be great fun. In reasonably comfortable conditions, we had great views of all the species mentioned previously and, in addition, attracted nominate race Great-winged and Solander’s Petrel, an out of season Slender-billed Shearwater, an adult SHY ALBATROSS, 3 Brown Skuas (including the unusual pale individual recorded the previous day), 3 Northern Giant-Petrels and a small flock of Wilson’s Storm-Petrels. Cape Petrel numbers seemed to increase every time we looked down the berley trail. The number of FAIRY PRIONS suggested that this species is making a resurgence into NSW waters.

    Our cruise back to port was relatively uneventful bird wise but altogether thoroughly enjoyable. The weather turned on a great show with a waterspout to our north and multiple vivid rainbows against the slate grey clouds, which provided a dramatic canvas behind the swarm of following seabirds. Close inshore we found two Humpback Whales that breached several times providing great thrills and an Australian Pelican to round off the list of species observed for the day. Interestingly, the aberrant first winter Kelp Gull observed in May joined us a few miles offshore and followed us back to the breakwall. Pterodroma numbers remained unusually low for the season.

    Highlights:

    The birds observed were very similar to the previous day ‘s trip but conditions were much more comfortable. Once again we observed of 7 species of albatross and the highest number of both FAIRY PRION and Cape Petrel for several years were recorded. The unusual Catharacta Skua reappeared and continued to draw attention to itself.
