Hi Peter,
There are some excellent images on Rohan Clarke’s website (taken by Adrian Boyle): http://www.pbase.com/wildlifeimages/baraus_petrel
And here of course some of the pictures taken last Saturday by Raja: http://www.adarman.com/Pelagics/New-South-Wales-Pelagics/2013-February-09-Sydney
There is a number of literature for either that species or similar species (to be ruled out): Howell, S.N.G. (2012): Petrels, Albatrosses, and Storm-Petrels of North America: A Photographic Guide. Princeton. • Marchant, S. & P.J. Higgins(eds) (1990). Handbook of Australian, New Zealand and Antarctic Birds. Volume 1: Ratites to Ducks. Melbourne.• Onley, D. & P. Scofield (2007): Albatrosses, Petrels & Shearwaters of the World. Princeton.• SHIRIHAI, H. (2007, 2nd ed.): A Complete Guide to Antarctic Wildlife. London.
Hope that helps a bit.
Cheers,
Nikolas
