My hop growing experience on Bribie Island was woeful. Research I did at the time indicated that you shouldn't really be growing hops North of Port Macquarie, not so much because of temperatures (it gets pretty damn hot in Central Europe where most Euro hops are grown) but because of day length.
They grow best with long hot summer days then set flowers as the day length decreases sharply in Autumn, which is fine in Tasmania / Victoria, but once you get into the Subtropical areas where there isn't a lot of difference between day length throughout the year I guess the plants don't get the same "trigger" to flower.
Some people seem to have had a fair bit of success, Nick B used to grow them at Nanango for example. I'd guess the best varieties to try would be ones that succeed in California, maybe Willamette if you can get them, as those areas are further South than Cascadia. (= our North)
