The Lions clinched a first series win since 1997 as they beat the Wallabies 41-16 in Sydney on Saturday.
"It's a pretty indescribable feeling," the stand-in captain told Sky Sports News. "There was a lot of talk about selection in the week. I think we proved that despite all the talk the northern hemisphere is doing pretty well.
"We fronted up today and I think the scoreline reflected it and we represented the four countries with pride."
The Lions' previous triumph on tour came 16 years ago in South Africa.
