I rode down from townsville via the New England. Did Tvl to Mackay in some of the worst weather I have ever been in. (Worse than the water filled goggles ride)

Did Mackay to Bris Vegas in one day then via Warick, Tenterfield Camped in a park at Willow Tree then Newcastle via the vineyards. Inland is a better route but to get to Buledelah you could slip down Thunderbolts Way. Don't know about it in the winter though.
