    Summary:

    A large anticyclonic system was located to the south of Tasmania that extended a ridge of high pressure along the New South Wales coast. The stable conditions produced the perfect morning for a late autumn pelagic excursion; cool and clear with gentle southerly breezes. Conditions were simply perfect as we left Wollongong Harbour.

    Black-browed, Campbell, Indic Yellow-nosed and SHY ALBATROSS were foraging close to shore and several Fluttering Shearwaters passed astern as we headed east. An unseasonably late POMARINE JAEGER was a surprise as we cleared the inshore reefs. A stunning adult BULLERíS ALBATROSS joined the following pack shortly afterwards and then within a minute another equally stunning individual appeared.

    It felt as though we had already enjoyed a great day at sea well before anyone tucked into the first of their sandwiches and then Brown Skuas appeared from all directions. Almost immediately afterwards Fairy Prions were all around us and, even before they appeared, Iím certain that somebody had already mentioned the fact that Brown Skuas are irresistibly attracted by flocks of prions.

    Our cruise eastward continued in the much the same vein; at one point there were 3 adult and one first year BULLERíS ALBATROSS following our vessel. SHY ALBATROSS were uncommonly abundant and at least two White-capped Albatross were also present. We set up a drift-and-berley session beyond the 200-fathom line despite the fact that we had not encountered any pterodroma petrels by this time. Instead we were treated to great views of Sooty Shearwater. Eventually a solitary Solanderís Petrel did appear but only for the briefest of views. By way of compensation several diomedea albatross appeared and after an hour or so we had attracted an impressive mixed species albatross flock.

    With the small but choppy sea behind us, the journey back to port was even more pleasant than the outward-bound leg and we added Pied Cormorant, Kelp Gull and a very late record of COMMON TERN to the list of species recorded for the day. At least one additional adult and another first year BULLERíS ALBATROSS followed us for much of the return trip and the surprise sea monster turned out to be an adult male Australian Fur-Seal.

    Highlights:


    The preponderance of Fairy Prions, BULLERíS ALBATROSS and Brown Skuas borne ahead of a steely cold southerly breezes were a crystal clear portent of the approaching winter but the late records of POMARINE JAEGER and COMMON TERN provided that unique mix of seabirds that gives late autumn pelagic cruises a special character.
