Hey Ponters.
Speak up if I'm pushin it too far for ya buddy but have a look at this for a revised trip plan.
Kick off (for you) Melbourne.
Bathurst. 780Ks
Grafton. 770Ks
Hervey bay. 612Ks
Maybe a bit further depending on the last route.
All and any wanting to group up could aim for Grafton on the Thursday night and ride thru from there with Tomcat and Mitch leading us on a diversion avoiding the Metropolis of Brisbane/Gold coast/ Sunshine coast.
