Grey Butcherbird?

This little fellow sat on my verandah balustrade for a few minutes this morning and I took his photo through the glass as I didn't think he'd stay if I went outside. I THINK he's a Grey Butcherbird. Maybe someone can verify. I've posted a view of his back as an extra to help with identification. He was a similar size to a kingfisher and much smaller than a kookaburra.
