just did the same trip (both ways)
perhaps you would care to share your experience now that you are "home" ..?
What did you do for accomodation? where did you stop, what did you enjoy the most.
We were impressed by the NSW policing of the roads..very consistent reminders the entire way (on both inland and coastal highways) of the dangers of speeding/tiredness etc. We hit no major delays and saw no accidents.
we travelled only during the day with a good number of rest/eat/play stops as we had a busy 3 year old and only one driver. The trip took us 2 reasonably easy days each way (as I am non driver you may say..."yeh easy for YOU" but be assured that entertainment director was the short straw) .We stopped in Armidale on the way up and Port Macquarie on the way down...accomodation in moderately priced motels (Country Comfort) booked either on the day or the night before without any drama although it was certainly busy.
Port Macquarie impressed us too...it would be lovely to stay at the new Sheraton there sometime soon...but the caravan park had THE best location...a little cabin there would be just fine too.Very kid friendly atmosphere.It helped that the weather was perfect...and the dolphins just capped it off.
On the way up we lunched at the the Telegraph (?) on the New England Highway...lovely spot and good food.
Coffs Harbour (lunch break) also had some great looking beach resorts but that Big Banana needs help! but perhaps its tackiness is an essential part of past and future childhood memories.We saw lots of BIG things (prawn, guitar,rock)...essential part of the experience.
this trip has certainly made us keen to take more time to explore the area more in future.For us both Sydney and the Gold Coast are "home" so our curiousity was more about the trip than the destination. it has been some 25 years since I had last done it.
