My 2c: It should be a separate category.
Light sparkling ale with a little maltiness and a solid hops impact on aroma & flavour but with minimal (smooth) bitterness, and virtually no yeast element other than a moderate attenuation.
Doesn't fit into any current category properly - it's not really a wheat (i disagree it has much "wheat element" and i'd suspect the %-age is quite low, despite what is frequently reported to be the %wheat); and is different to typical milds. Too light to be an APA & bitterness is too low, no yeast element and too strong in hoppiness to be an Aussie Sparkling Ale. Not sure wtf an UK Summer ale is. Is close to a British Golden Ale, but i'd wonder if the hops elements are quite (distinctly) different to what is typical for BGA - similar to the difference between an English Pale Ale & an APA, which prompted the recognition of a new style, the APA.
Time for a new style: Pacific Ale.
FWIW, i've already added a customised entry into my ianh spreadsheet for Pacific Ale:
Aussie Pacific Ale 1.030 1.045 1.005 1.015 15 35 6 10.0 3.5 5.0

I'm not sure where i got these specs from - i think i might've cobbled them together a bit, so grats to whomever the sources were.
