Fox made history last year on the same course becoming the first female paddler to win gold in the C1W and K1W events at the one World Cup.
Fox, who celebrated her 20th birthday on Wednesday is on track to repeat that amazing achievement with the K1W event still to come tomorrow.
Fox headed into the final having earlier recorded the second fastest semifinal time behind fellow Australian Rosalyn Lawrence.
But when it mattered most Fox simply dominated the technical 24 gate course, executing a clean run of 120.69 to finish more than 15 seconds ahead of her nearest rival.
Czech paddler Katerina Hoskova took home the silver medal in 136.12 with Qianqian Teng of China collecting the bronze.
A mistake on the first gate proved costly for Lawrence as she was forced to try and make up time through the middle and lower sections of the course. Despite her best efforts she had to settle for fifth, 26.51 seconds behind Fox.
Earlier in the day Alison Borrows had a run to forget incurring 206 seconds in time penalties to finish 14th in the semifinal.
Armidale’s William Forsythe produced his best World Cup result finishing sixth in the K1M final.
The 27 year old couldn’t quite sneak onto the podium with two gate touches on 14 and 19 relegating him out of medal contention.
He finished 7.58 seconds behind German Fabian Doerfler who went one better than last year to win the gold in 97.12, 0.20 seconds ahead of Italian Andrea Romeo.
A second German Sebastian Schubert collected the bronze.
Earlier in the day World Cup debutant Daniel Watkins of Hobart finished 35th in the semifinal. The 18 year old showed encouraging signs for the future.
In the C1M event two Australians recorded top 20 results with Ian Borrows narrowly missing out on a place in the final in 12th while Victorian Christian Fabris produced a career best result finishing 19th.
The final was dominated by the host nation with Benjamin Savsek winning the gold in 104.94, 1.12 seconds ahead of Slovakian legend Michal Martikan.
Slovenian Luka Bozic edged Italian Stefano Cipressi for the bronze by 0.07 seconds.
