Darwin has an extensive public bus system that services most suburbs from the inner city to Palmerston. As a student, you can purchase $1 tickets for three hours of travel, or better still buy a weekly ticket for only $7.
Flat terrain and cycling paths make for easy, safe, walking and cycling in Darwin and surrounds. More information on Darwin's bicycle paths can be found on the NT Government or Study NT websites.
Driving a car or motorbike is another option. Alternatively, Uber and other ride-sharing services are also readily available in Darwin.
