Yes, apparently White-phase Wedge-tailed Shearwaters are
unknown at much larger colonies north and south of Shark Bay and only
recorded at sea within a 200-300 kilometre radius of Shark Bay (Wooler et al.
2005). Here are a few papers on this topic (including Serventy 1972):
Serventy D.L. (1972): The Shearwaters of Shark Bay, WA. Emu
72: 175-177.
Lane S.G. (1972): White-phased Wedge-tailed Shearwater on
North Solitary Island, NSW. Emu 72: 184-185.
Wooller R.D., Bradley J.S. & Powell C.D.L. (2005): Plumage
dimorphism in Wedge-tailed Shearwaters Puffinus pacificusin
Shark Bay, Western Australia. Corella29: 49-50.
Davis W.E. Jr. (2006): Plumage dimorphism in Wedge-tailed
Shearwaters Puffinus pacificus in Shark Bay, Western Australia. Journal of
Field Ornithology 77: 92.
(This article is a summary of Wooler et al. 2005)

Subject: Pale morph Wedge-tailed Shearwaters in WA
Looks like the source of the error is HANZAB which in its Wedge-tailed
Shearwater account says in the first paragraph " light morph rare in e.Aust and
NZ but composes about 20-30% of population in w.Aust."
