Perth will host the Australian road cycling championships for the next three years in a major change to the sport's summer calendar.
National governing body AusCycling had confirmed in July that the event would move from its long-time home at Ballarat.
Monday's announcement confirms weeks of speculation that the nationals are going to Perth.
While course details were not outlined in the release, the road races will be held at Kings Park.
Perth last hosted the event in 1997.
Two years later, long-time Victorian race promoter John Craven revamped the nationals, basing them at Portarlington near Geelong from 1999-2001.
He then took the event to Ballarat and nearby Buninyong, which featured a hilly circuit that sharply divided opinion.
While Ballarat and Buninyong proved a masterstroke in terms of profile and crowds, there have been annual complaints from riders that the Buninyong circuit gave sprinters little chance to win.
Apart from 2005-06, when the nationals were held in the Adelaide Hills to combine with the Tour Down Under, Ballarat has been the venue since 2002.
Perth has a strong cycling culture, with current stars such as Giro d'Italia winner Jai Hindley, Tour de France contender Ben O'Connor, Olympic track medallist Sam Welsford and Luke Durbridge hailing from the city.
There was also significant change to this month's racing calendar, with the long-running Bay Classic criterium series in Victoria cancelled because of funding issues.
Confirmation of the new nationals venue comes a day after Welshman Stevie Williams won the Santos Tour Down Under, the sport's biggest annual event in Australia.
Race director Stuart O'Grady said he was "really, really happy" with the major changes he made to this year's Tour, including summit finishes for the last two decisive stages at Willunga at Mt Lofty.
For all of O'Grady's efforts to add new elements to the race route, defensive tactics were prominent this year as teams sought their edge.
"I can't influence how the guys race it,'' O'Grady said.
"I was surprised they didn't go harder on the second ascent up Fox Creek (in stage two).
"Speaking to the teams, they were all 'we were waiting for someone else to attack'.
"Then stage four (to Port Elliot) was designed for crosswind, and for the first time I can remember we didn't have any actual wind down around Alexandrina Council.
"But also the speeds they're going up climbs, it's hard for people to attack.
"It's a real balancing act - marking the race hard, but also not too hard, being the first WorldTour event in January."
O'Grady is well advanced on planning the course for next year, which will be the 25th edition.
"Of course we want to do something a little bit special, we want a bit of surprise and delight for the 25th edition," he said.
