You Queensland guys are welcome at Grafton anytime.
It never gets really cold at Grafton so sailing in the Winter is an option. Like all inland places the wind at Grafton is unpredictable but it does tend to die off during the Winter. So if you are going to come down you would be better advised to come not in the Winter.
Having said that, if you want to come down in the next few months we will definitely meet up and sail with you.
