For the first time this year a two-day format was used, which saw Crawford qualify fifth fastest on Saturday with a 1m46.356s lap-time.
A clinical performance in the first moto by the KTM 250 SX-F rider saw him lead each lap en route to a dominant 12.880s victory.
Choosing to play it safe in the second moto, Crawford led the opening laps before taking the chequered flag in P2, comfortably securing him the overall victory.
Meanwhile in MX1, Kirk Gibbs qualified in fourth place after leading the early stages of the Top 10 Shootout on Sunday morning.
A strong start saw the 33-year-old slot into second place following the opening lap of moto one, eventually finishing the bout in fifth position.
The KTM 450 SX-F rider went one better in the final moto of the season to cross the line P4, landing fifth overall at round eight, where he also finished in the 2022 MX1 standings.
Coolum also saw KTM Junior Racing Team rider Kayden Minear claim a maiden national MX3 crown, the 15-year-old clinching the title aboard his KTM 250 SX-F in convincing fashion this afternoon ahead of Ryan Alexanderson.
Nathan Crawford: “I only got to come back for three rounds, but they were probably three of the most special rounds that I have had. It’s the biggest honour to work with a team like the KTM Racing Team - everybody in the group is second-to-none. I’m super-stoked at the results we can achieve and I put it down to those guys, sticking by me when I was injured. The first moto here was really good and the second moto I got a good start and led for the first 10 minutes or so. Then I realised it wasn’t anyone around me who was strong in the first moto, so I decided to take the high road and take a little bit less risk. I sort of sat back and let Levi [Rogers] go by and just rode it home for the overall.”
Kirk Gibbs: “It was an okay day, I went 5-4 after two good starts this afternoon, but just struggled a little bit with intensity and the lead guys were a little bit faster today. It is was it is, we've just got to move on and move forwards and, considering the injuries I've had along the way this year, I can finish the season happy.”
