I think Pacific Ale is one we can run with. Light grain bill, pale colour, good head retention. Sessionable, 4-5% abv, maybe you could go even lighter. Hop forward, majority of IBU's gained from late hopping, showcasing fruity characteristics of new Australian hop varieties such as Galaxy, Summer, Ella etc. As a 'Pacific' Ale, maybe NZ and even US (as if they don't get enough of a look in) hops could be used as well, for the same purpose. I used Wai Iti with Galaxy in my Pacific Ale and it complemented the passionfruit with a citrusy quality. Mmm. Maybe you could even add the pear-y flavours from the Coopers yeast?
Uses largely Aussie ingredients to produce a beer that's ideal for enjoying throughout the afternoon on a hot Summer day. How Aussie is that?
