VFR just go direct depending on weather, if you're IFR and want to do it all fancy track Dun to Laravale to Armidale to Tamworth. With the Airspace around there I'd just suggest going VFR if the day is nice enough for it and stay clear of the Airspace as you'd be pottering through a few different common entry routes from the south or track VFR to Laravale to clear the Brisbane and/or Gold Coast traffic then pick up IFR from there.
