Hi Kalle.
Can you tell us where you are on the gold coast? Do you have equipment?
If you don't get many responses, it's not because no one is interested in helping, it's mainly because most of the people who manage to sail during the week have slipped away from work for a couple of hours and may have limited time - it would probably be difficult for most people to pick someone up and still have time to sail while the wind is there.
The wind is a bit unpredictable in SE queensland and you need to get it while it's there
(be ready to go at the drop of a hat) and be happy with a couple of hours of okay wind. If you can do this, you can usually sail a few times per week, maybe more.
11am to 4pm is generally the strongest wind for the day
