Territory Day went off with a big bang this year.
In addition to an explosive performance from Australian pop duo The Veronicas, and a cracking fireworks show, this year marked 40 years since the Territory attained self-government.
The celebration attracted what could have been the biggest event Katherine has seen.
Many hundreds of people gathered on the grass at the Showgrounds for the event.
Amazing performances from Australian musician Craig Phillips and Darwin-born rhythm and blues singer Caiti Baker on top of The Veronicas, had the town dancing the night away.
Chair of the Jarwoyn Association, Lisa Mumbin, also delivered a powerful Welcome to Country to open the event celebrations.
Territory Day 2018 saw firework sales like no other for the one night of the year crackers can legally be set off between 6pm and 11pm.
The town was lit up with masses taking to the streets to light up their explosives.
More than 300 tonnes of fireworks were imported into the Territory for the big day, an NT Worksafe spokesperson said.
The largest distributor of fireworks in Katherine, Max Brunner of Fireworks Warehouse, said over 10 tonnes were sold in Katherine.
Selling his fireworks at Katherine Camping and Fishing, Mr Brunner said he was sold out by 1.30pm.
