No they are indeed Summer hops. I found them at Austin Homebrew Supply here.
They are an Australian hop as is the Nelson Sauvin hence the name Aussie Amber. The flavors aren't too terribly different from each other in the citrus aspect but the AA range is quite different. I'm curious to see how your beer turned out.
I used Bear-flavored's hop guide here
to develop this recipe with some fruit forward hops. I will definitely be doing this beer again but I might try and do half with some extra hops in it towards the end to experiment with the flavor a bit.
