Since you indicated in your other post that you are travelling in January, I would recommend you use the Australian (and European, and UK) date format - day/month/year to reduce confusion and get more useful answers.
I am pretty sure that others will also suggest to plan to travel from Melbourne to Adelaide in 2 days leaves you virtually no time for sightseeing, to make it worthwhile. Even via the most direct inland route, its still takes about 9-10 hours including some basic food/refueling/comfort break stops. To detour via the Great Ocean Road it would usually be recommended to allow at least 3 to 5 days:
The other significant consideration is that January is peak season and right in the middle of the Australian long school break summer holidays, so bookings along this popular route are highly recommended as soon as possible.
Not really feasible. For all the reasons in post #1.
It will take most of the day to drive to Mt Gambier if you drove the inland route to Warrnambool with only a brief side stop via Simpson to The 12 Apostles and Port Campbell. This would miss the most scenic drive but you could visit Port Campbell.
But you will have no time to stop and enjoy the sights in any meaningful way.
Accommodation in Mt Gambier is probably going to be ok if you book soon. Anywhere else you are likely to have to take what is left.
Agree with #1, #2, #3 and #4. It's a waste of your precious holiday time trying to drive so far in such a short time. Suggest you look at sweetbiscuit's suggestion in #3, but first check that you can find a single night's acommodation in Apollo Bay in what is our absolute peak season.
I want to Thank everyone for the information you all have provided and now we are looking at an alternative route. We will be leaving out of Point Cook, Victoria down to Torquay, then possibly stay the night in Horshan, then day 2 finish the drive to Adelaide. According to Google maps it should take a total of 9 hours driving time. That should give us a little Coast line sight seeing and then allow plenty of other sight seeing along the way both days? Any additional information would be Greatly Appreciated, Rick
To be honest and I might be only one voice on this I don’t like the idea of driving from point cook to Warrnambool and onto Horsham via the GOR in a day at all. That equates to about 9 hours of solid driving without a stop factor in a bit of sightseeing you are potentially looking at a 12 hour + trip and then you’re going to continue onto Adelaide the next day.
The GOR especially from Eastern View through to the 12A is a challenging route. Quite narrow with many hairpin bends plus ongoing road works to contend. After spending about 9 hours on the road we’re looking for somewhere to prop for the night and that’s even with rotating drivers every couple of hours to make sure we had a fresh driver at the wheel.
It’s your trip and I hope it works out for you.
Safe travels.Edited: 19 October 2017, 20:25
When google maps says nine hours, it is not accounting for sightseeing stops, toilet stops, heavy traffic. And road works. Famrick is right, you will be more than 12 hours on the road and anyone driving that length of time on unfamiliar winding roads is putting themselves and others in danger. Whoever is driving won't get to enjoy the views at all if they are doing theirjob and concentrating on the road. It is a waste of your holiday time to do this.
Once past Hirsham you can look out for the bakery at Kaniva for vanilla slices. Stop for coffee at Keith. Dog park and grain silos near Tintinara oooh and the superphosphate memorial before you get to Murray Bridge.
