Strop is right on the money - the drive times seem a bit ambitious. You're covering in excess of 1800kms - something that would take almost 20 hours non stop - and thats not counting lone pine, wheel, and any further trips down to the GC. Somethings to ask: Are there specific reasons you want to go to Bundaberg, Airlie Beach, Rockhampton? The reason I ask is you seem to be spending almost zero time in Bundaberg and Rockhampton, and they appear to be waypoints on your way to Airlie. What's the attraction there, as there may be alternatives that are far closer. You may also want to fly domestic - as you'll save loads of time and have more time for the fun activities. What are your 'must do' activities? So far i see a reef cruise, lone pine, the wheel, and presumably - parks. Is there anything else you want to do? Perhaps have a chance to rest?
