what's this bird

Hi:I recent visited your country one week ago.I have traveled Sydney,Brisbane and Cairns and took many bird pictures at each place.I have bought a Australian bird guide by The Slater.I can identify most of the bird through this bird guide.Still a few bird I have difficult to identify.One of them is the picture I took at Blue mountain National park near three sisters.I think it's more or less like grey shrike-thrush.Please help me to find the correct name.Thanks
