Travel the Great Ocean Road

I fly into Melbourne arriving at about 8AM local time.  I rent a car and re-learn driving on the left while I drive the Great Ocean Road along the Victorian coast southwest of Melbourne.  It has gorgeous surf and sandy beaches. 
Although further west some of the shore has higher rocky banks.
This area is popular with surfers although in some areas there is too strong an undertow.  This surfer was never able to get up while I was watching.
Further west we come to the Twelve Apostles.  This famous formation is an icon of the State of Victoria.  The "apostles" form when the relatively soft back is erodes and leaves a part standing.  Then bank is eroded back several inches per year.
The first night I stay at the Quimby Homestead.  This was the primary house for a large farm in the 19th century consisting of several thousand acres.
The next day I visit the reconstructed Flagstaff Hill Maritime Village in Warrnambool...  All the buildings are original although most have been moved to this site. The fishing ships were primarily at Port Fairy 29 km west while this harbor was used for shipping the farm products from the farms to the north (like the one where I stayed the previous night).
The lighthouse was moved from its first location, near the beach, after about 10 years, because the surf spray often obsured the visibility from ships.  It was moved to this location in the mid-1800s and this model village was built around it.  To the left of the lighthouse is the lighthousekeeper/asst keeper's house.  It was divided down the middle.  Each keeper took alternating four hour shifts. 
The keepers often had large families (6-15 children) and so there were lots  of babies.  The chair below has only one arm to better suit nursing.
After visiting the village I drove north through the Grampians Mtns and National Park.  The mountains rise rather abruptly from flat farm land.
All through the park I was tantalized by signs warning me of kangaroos, emus and koalas crossing but I never saw any.  I think that they were just there to trick the tourists (or perhaps these animals are not active mid-day).
