Waiau is actually a New Zealand herd, and while Eldorado was never used here in Australia, he is sired by an Australian bull GVPC Kernel.
Kernel had great eyes, colour, soft coat and outlook and was renown for the females he produced. Many sires used by studs here in Australia were out of Kernel cows. I beleive Bill Bennett imported semen so he was also used in the States. He didn't have enough back end and thickness for us to ever use his blood much though.
