Hi there, you don't have much to go on so I had a look at the stations website and they are running a weekend destinations competition with the prize changing each week and this week it's to Port Macquarie. Have a look at
http://www.973fm.com.au/win/2010/09/03/destinations-weekend-getaways/ which is the entry form for this week, it's a 25 wol but might jog your memory. But congratulations. The other way might be to google your name and 'winner' and hope they've posted the result somewhere. I tried 'contol+f' at the calendar page and entering Couran Cove but that doesn't bring anything up either. Hope you find it.
