I would suggest that you stop in Lorne quick to get to lovely beach and atmosphere. Then I would drive the rest of the Great ocean road taking in all the sites at your leisure. I would only recommend that you make it Port Campbell to check in and go back to the 12 apostle viewing site for sunset, as there is a colony of 20 - 30 penguins that come in just after sunset. The next day continue to map out other attractions close to Port Campbell for example grotto, London bridge, and of course Loch Ard Gorge. Then make your way back to Lorne for another night, in my opinion, to relax prior to continuing your travels.

if you are in Melbourne, you can find the travel agency in china town, they provide the service everyday. there are more than one agencies in china town. search the the name EXTRAGREEN or GRANDCITY with google, you will find their website and book the package, you can also go to their office to book the package and ask questions if you like.

I did see a few buses along the route, but felt like they were big tour buses. As for accommodation, we rented a house for 3 days. There are some smaller hotels around. Not sure on nightly minimums

A hire car if travelling from the airport, or maybe a bus tour. If driving, remember that the roads can be difficult and tiring. Accidents are common.

Free

There are plenty of good photographic vantage points but yes there are restrictions as to where you can walk to limit damage to the landscape. I have never found these limiting in getting some great photos at sunrise or sunset. During the day you may want to consider ND filters if the sun is bright.

Sono più di 800 km. Non ne vale assolutamente la pena, in quanto ti perderesti tutte le meraviglie della Great Ocean Road. Fuori Melbourne c'è la Belt Beach, una meravigliosa spiaggia conosciuta come la migliore del mondo per fare surf. Qui ci trascorri almeno 1 ora o 2 per camminare sulla spiaggia. La GOR da Melbourne a Port Campbell è lunga quasi 250 km e vale la pena soffermarsi nelle diverse baie. La si percorre ad una velocità media di 50 km orari ed è meravigliosa. Per arrivare ai 12 Apostoli, da Melbourne ho impiegato 9 ore. Dopo i 12 Apostoli il panorama cambia e potresti raggiungere Adelaide in una giornata.
