Drewgong, I highly recommend joining the Aussie Hop Head Chat facebook group. Stuart and Brad that admin the group are commercial growers/horticulturists and have a wealth of information and assistance to offer. I live in the Hunter Valley and had a good first year. I've got chinook and cascade which seem to love it here, especially the chinook went nuts. Got about 400g off it this season, I even took a green cutting off it just because I could which has established itself well. Seems to be the right climate here for them
