I enjoy going to Port Arthur and have been many times. I believe this cute cottage is the Shipwright's House.
According to the Port Arthur website: This house (1834) was one of the first buildings in the dockyard and was built for the Master Shipwright, John Watson and his family. Following the closure of the dockyard, the limekiln (1854) next to this building, was built to burn shells and limestone for lime that was used in mortar and plaster, as fertiliser and for the tanning process during the convict era.
