Dunno if this will work, but just a suggestion:
Queens Bday falls on a Monday this year, so was wondering.
If DTM Syndey members go ahead with a cruise say on Queens Birthday long weekend, would anyone in Melbourne be intersted in possibly tagging along to Sydney for that weekend?
Thinking of making a trip up some time and if we could get a group would be awesome...
Edits:
-Leave on 10th Sat of June around Midday
-Group Stay at hotel
-Clubbing, bars pubs you name it
-And anything that eventuates
-Arrive back by 12th Monday (queens birthday) back in Melb by 8pm.
Dont get overly excited

Just preliminary ideas, but the idea would be say leave Melb around 9am-12pm Sat Morning, getting to syd by evening (about 800 Kms), clubbing sunday night meeting up with syd members, and heading back on Queens Bday morning/midday.
All up would be about 2000 highway Kms on your ride, considering you do around 600-800 on the cruise, suppose would be priceless for the experience hence only for the DIE Hards.
Wiked idea dont you think...
