Mark Nawaqanitawase concedes it's "mind-blowing" to think he could win an Olympic gold medal before jumping codes after making a late charge into Australia's rugby sevens team.
The Wallabies winger has signed with the Sydney Roosters and could play for the Tricolours this season after the NRL cleared the move on Tuesday.
The former NSW Waratahs flyer will be hoping to bring some silverware after securing selection in John Manenti's side that will arrive in Paris among the many contenders for gold.
While former Wallabies captain Michael Hooper's bid fell short, Commonwealth Games representative Nawaqanitawase's raw speed and athleticism was enough to earn him a spot in the 12-man squad named on Wednesday.
Manenti said he planned on using Nawaqanitawase's X-factor in explosive short bursts.
"His aerial skills are huge in sevens," Manenti said.
"Kick-off reception and kick-off restarts, so that's a big weapon for him.
"His offload game. He's a big body, the biggest body we've got, so his engine won't be as well-trained as the guys who have been with us for a long time.
"But he'll be able to make an impact in three or four-minute bursts and hopefully win a kick-off back and suck two or three guys into the tackle. Give us the opportunity to play off that."
The 23-year-old admitted it was a surreal feeling knowing he could potentially go from being a member of Australia's worst-ever Rugby World Cup team and picking up a Super Rugby Pacific wooden spoon with the Waratahs to collecting an Olympic gold and winning an NRL premiership in less than two years.
"It's been quite a crazy year," Nawaqanitawase said.
"It's mind-blowing to think this was even a possibility."
ACT Brumbies winger and former sevens regular Corey Toole will also play in Paris, able to prove himself alongside Nawaqanitawase in a last-ditch June training camp.
"His speed gives us a real point of difference," Manenti said.
"Even in training, he's just starting to get back into his groove from where he was last year, two years ago.
"Certainly from our end (he's) the quickest thing we've got."
While it was joyous day for Nawaqanitawase and Toole, Maneti said it was tough telling Hooper he'd missed out, a year after the former Wallabies captain was also overlooked for the World Cup in France.
"He gave it every shot," Maneti said.
"He was really strong in our last tournament in Fiji, so ultimately he probably ran out of time.
"He didn't have enough chances to, I suppose, undo the hard wiring that he had from 15s.
"But he's been excellent around the group and offered a lot so that was certainly A tough conversation.
"But he handled it like the good guy he is and took it really well and he's really happy with the squad that we've picked."
Rio gold medallists Charlotte Caslick and Sharni Smale, as well as Nick Malouf and Henry Hutchison, will become Australia's first triple Olympians in rugby.
Australia's men finished fourth in the world series while the women won the title.
