JESUS! - Thats Waaaaaaay too much Crystal.
While I live in NZ and haven't had this beer, I have been to the brewery on a trip
Their beers tend to be very dry, and overly bitter, with massive hop aroma and flavour.
so huge amounts of dryhops.
For example google the Stone Ruination or Stone IPA - Minimal Crystal, no more than aroudn 1lb normally in a 5g batch.
The "gold" descriptor suggests pale malt and possibly a light colored crystal.
Although their Delicious IPA is Pale Malt Munich and Vienna - No Crystal.
Vis Secret and Ella are great hops, I'd go with 2oz of each in the dryhop.
Galaxy at flameout in conjunction with other aussie hops.
Oh and FYI Southern Cross is not an Aussie Hop - Its NZ (I should know)
Id go
1lb vienna
and 0.5lb crystal 20
make the balance up with Pale Malt
WLP007 is the closest to house yeast they do.
bitter with something neutral (magnum etc)
then a 30min addition and a hefty flameout
(Possibly 10 mins as well)
followed by a ridiculous sized dryhop for 3-5 days.
and you will be in the ball park.
