Shmeleva (18) claimed her fourth gold medal of the championships in winning the women's 500m time trial in 34.753sec, which broke the world record she set at the recent European Championships by 0.1sec.
She finished with one more gold medal than outstanding Australian prospect Taylah Jennings who won all six disciplines on the way to winning the omnium, along with the team pursuit and points race.
"I am very happy with that ride. I had a world record last month and it was very good to go faster today, especially as this was the last day. It was a very good championship and it was such a long way to come that it was more special. I like the track very much," Shmeleva said.
Australia finished on top of the medal table with 16 medals, including nine golds. It won two on the final day. Outstanding sprinter Jacob Schmid added the keirin title to his sprint gold medal .
He outclassed compatriot Emerson Harwood in the final.
Czech Jakub Vyvoda was third.
"Really ecstatic. It's unbelievable.
"I can't have imagined anything going better than it has," Schmid said. "Our work ethic, our professionalism and our dedication with the work hours we put in is the key to our performances this week."
The other victory went to Kelsey Robson (16), who blitzed her way around the track to win the women's individual pursuit in a slick 2min 23.573sec.
Elinor Barker, of Great Britain, was more than 2sec back in second and Australian Georgia Baker third.
"It's pretty incredible. Coming into it, I didn't really expect too much, being in my first world championships. I think there was basically no pressure on me because I have another year in this category, so to just come out with the win is so good. It's pretty unreal," Robson said.
The championships wound up with a brilliant performance from the Colombian pairing of Fernando Gaviria Rendon and Jordan Parras Arias who won the men's 30km Madison from Belgium and a gallant New Zealand, whose Dylan Kennett recovered from a heavy crash to pick up his fourth medal.
On Saturday, Kennett, of Waimate, earned his third silver medal of the championships in the 3000m individual pursuit.
Kennett was beaten by outstanding Swiss rider and top qualifier Tom Bohli in the gold medal ride-off.
Aucklander Racquel Sheath secured her second medal of the championships with a bronze medal in the women's six-leg omnium, following her silver in the team pursuit.
