I did stay in Port Fairy in 2020/2021 but haven't been to Moyne Cottage in over a decade.
It was the same as I remember. Big comfortable rooms, lots of optional entertainment (games/dvds/books/local guides). All the supplies you need to cook up a good meal.
As always the bonus of staying on the Moyne River is the views of the water no matter the weather, being near the beach, the different flora and fauna. If you stay in the front bedroom you will have those glorious river views. If you stay in the back you can hear the ocean at night, it's a hard choice!
It's not a fancy hotel and it doesn't claim to be, I think anyone who wants comfort, space, easy access to amenities and something with a bit of history will find this cottage perfect.
