Sarah Island is accessible via cruise boats which operate on Macquarie Harbour out of the west coast village of Strahan. There are several cruises every day of the year. These cruises also continue up the lower reaches of the beautiful Gordon River, and often take in the narrow entrance to Macquarie Harbour, known as Hells Gates.
Yachts can also be chartered to reach the island.
Strahan is reached via the B24 from Queenstown. If you are coming from the north along the Murchison Highway, turn right on the B27 to Zeehan and follow the road for 46 km through to Strahan.
