The cheapest flights in the past have been Feb/March and Sept/Oct.
Around the $130 return + luggage. Some specials may occur until about mid June, however after this School Holidays kick in with the NT having 4 weeks.
Subscribe to Jetstar and monitor the 2013 specials that way you have an idea for 2014.
