On the Sunday night, hip-hop trio Bliss n Eso, Thundamentals and Mallrat will bring the event to a close.
On-track, the Virgin Australia Supercars Championship will be accompanied by Porsche Carrera Cup, Touring Car Masters, Aussie Racing Cars, Improved Production and HQs.
The event will also feature an expanded family offering including the Disney Fun Zone and Disney Pixar Cars, Australian Defence Force Display and RAAF Flyovers, the Hot Wheels Stuntz Team and ShowTime FMX.
“The 21st Birthday of the CrownBet Darwin Triple Crown will be a celebration of all things Darwin, with fan favourites alongside a fantastic family offering at Hidden Valley," Northern Territory Major Events GM Tim Watsford said.
“This year is all about the fans, with more value for money at the event, as well free activities in the city centre during event week.
“With free general admission entry for all children aged 13-and-under with a paying adult, the CrownBet Darwin Triple Crown continues to be an event for the whole family.”
