If you are heading home maybe drive south to Beaudesert.
From Brendale, take Bracken Ridge Road east to the Gateway Motorway, head over the Gateway bridge, keep right at the M1/Gold Coast turnoff and follow the Gateway Motorway to Logan Motorway that heads to Ipswich and Toowoomba. 500 m after you get on the Logan Motorway, turn south to Beaudesert on Mt Lindsay Highway. Head straight south though Beaudesert and take the Duck Creek Road back road/track to O'Riellys. Check out this awesome place, do the treetops walk, have lunch or afternoon tea and then head for Canungra via the bitumen. Stop overnight at Sharp River Bend a couple of km out of Canungra and it will cost you all of $5 per person. Here's Macca, Brendon fro the Phillipines and I (from NewHilux forum) at Sharp River Bend kicking back before kicking the camp oven into gear.
The next morning pack up and head for Pebbly Beach in the South end of the Yuraguiar National Park just north of Coffs Harbour. Time your run with the low tide, drop onto the beach for a couple of km, and cross the tidal creek to the camp ground. You'll get your CT up the bank on the other side no worries.
I gotta thank the 4WD Action guys for showing me this place and here they are setting up for a cover shoot in a real campsite. Awesome hey!
The ranger will come around and collect your camping fees.
From here you are on our own to get home! (at low tide the next day... or the day after...
)
