The two-time junior road race world champion hung on to the wheel of Wild for dear life in the final kilometre and edged the Dutch powerhouse over the line.
Dideriksen who rides for trade team Boels-Dolmans was surprised by her win.
"I was hoping for the top 10. It's a surprise for everybody. I knew the Dutch girls would lead out Wild and I wanted her wheel so bad. It paid out. I'm in a sprint taking out the world championships. Unbelievable.
"I've won twice as a junior and I've taken this at 20-years-old. I'm really happy."
Each member of the Australian team raced vigilantly for leader Chloe Hosking but were caught out in the closing kilometres once the seven rider Dutch train launched, Hosking left alone for at least 1.8kms and sat around 15 riders back.
Hosking clawed back to sixth wheel by the last 500m but was unable to get out of her saddle, finally succumbling to the Doha heat and the relentless pumelling from the Dutch team with 70kms still to race.
How it unfolded
Japanese rider Eri Yonamine fired up proceedings with an attack from kilometre zero, her lead out to 30 seconds at the end of the first lap. She was joined by Switzerland's Nicole Hanselmann on lap two and the pair led until 70kms to go.
After the catch was made, the Dutch team capitalised on a Amy Pieters attack made only kilometres before by launching relentless move after move until the final 11 kilometres. Olympic or World Champion - each rider took their turns for Wild.
Earlier, Wild crashed but was able to make it back on
Rio Olympic time trial silver medallist Olga Zabelinskaya was disqualified after she took a bike from the side of the road rather than team or netural service cars.
Controversy follows the Russian who won a last minute reprieve from the Court of Arbitration of Sport (CAS) to participate in Rio.
Zabelinskaya, who served a retroactive doping ban for the banned substance octopamine, formed part of the IOC's blanket ban on all Russian convicted dopers participating at Rio. CAS ruled this unenforceable and Zabelinskaya proceeded to Rio while she awaited the outcome of a tranche of appeals.
