Thanks guys, that was all really helpful!
Having done this trip myself recently with some mates, I can give you some insight.
2 of us left Sydney early Friday morning, rented a camper van from launy and drove to Derby. Set up at the camp site by the river, Bikes built, some lunch and got out for a pedal Friday arvo.
The other 2 flew from Sydney later in the arvo (Jetstar 3.30pm flight ish), they rented an SUV, and got to Derby, checked into their accommodation, built bikes and were in the pub before 8pm.
We all rode Saturday (shuttle Blued Tier and Atlas) and rode Saturday evening from the trail head.
Sunday was an early morning ride for all, with 2pm shuttles to Blackstump.....
2 others had a flight from Launy at 8pm ish, so packed the bikes away and headed off to the airport.
The other 2 drove the camper to Launy with the intention of getting on the piss...... but ended up crashing out as we were too buggered after all the epic riding.
We flew back on Monday morning....
Moral of the story, next time I go it will be a Friday arvo flight, back Sunday night. I did get some extra riding in on Friday, but at the cost of 2 days off work. Also, I'd go for accommodation over camping (even tho I love camping) as it less hassle.
The 2 that flew Fri/Sun had an epic weekend with 1/2 the hassle.
