I make the trip from Townsville to Airlie fairly often and it is always nicer to have someone to travel with. If you are planning ahead and would like to travel on a weekend after the 14th October feel free to check if I am also heading that way.
Stopping in Ayr or Bown for a pie from the bakery is nice if driving around lunchtime. Though if traveling later in the day I usually drive straight through as it's not a long trip. No worries at all if you would like to stop at a service station for a break, in no particular rush.
If you are offering to split fuel costs its about $30 total for the trip, for the car, so we could divide that evenly. But no worries if you need to save cash as I am traveling anyway. I have room for 3 passengers assuming you have 1-2 bags each.
