If you live over on the City side of the Harbour Bridge but still want to come to the Devonport Craft Market today, why not catch the train and then hop on a ferry over to Devonport? The trains are free see here . The market venue is just a short walk from the ferry building. You can see a map here or ask a friendly local.
The market is on today, Sunday 5th September, 10-2, 32 Clarence Street, Devonport.
Have a great day!
