Sorry, I did a 2-day tour. The first day was up Great Ocean Road and the second day was Grampians. I can’t say for the 1-day tour since I didn’t do it. But on the first day of the tour I did (GOR+Grampians), we went to the chocolate factory, GOR memorial arch, Big Hill, Apollo Bay, Melba Gully State Park (skipped Otway National Park), 12 Apostles, Loch Ard Gorge, London Bridge, and 2 other stops. So about 10-11 stops? Pretty good for a day out.
