We booked this tour on a bit of a whim as it combined the 2 places we wanted to see and we were nervous about joining a small group because of covid. We were very thankful we did it this way. The element of it being private really worked for us. It particularly worked well for this tour because both days were jam packed of things to see and do. I could not have imagined trying to do this itinerary with a small group. It would have been rushed and just not as enjoyable. Our guide James took us to both areas and knew them both incredibly well. He was really friendly and knowledgeable and was always checking up on us to make sure we were enjoying the tour. The only thing that could have made this better was to see everything over 3 days. This was an option we had considered originally but we were constrained with our available dates. That said, we saw all the main bits of the great ocean road, but I felt there was even more to discover with an extra days. Although we just finished our last day before Melbourne went into a snap covid lockdown, so I dare say our 3rd day would have been cancelled anyway. We were absolutely both recommend Posh Penguins for a private tour to not only Phillip Island, but also the great ocean road.
