Sooty Shearwater?

Sooty Shearwater?

Observation - Sooty Shearwater? - Global. Description: I saw around fifty of these shearwaters whilst on a whale-watching trip outside Sydney harbour. I think that they are Sooty, but would welcome any comments/confirmations. The birds were between one and three miles offshore.
