Junee have secured their place in the 2022 Group Nine season after being voted in by their rival clubs at the annual general meeting on Sunday.
The Diesels have committed to having two senior grades next year, paving their way for a return.
Last year the club did not fill first grade or under 16s teams, but president David Holt is confident it will be a one-off.
"There are a lot of people within the Diesels who will be pleased as many were slightly uneasy of the direction we were going in," Holt said.
"Now there is some certainty and people were waiting for it to happen."
Group Nine chairman Andrew Hinchliffe, who was returned for a second term, is pleased to have more clarity on Junee's situation.
"It's really good to work out where Junee is at and now that we understand we have nine teams it gives us some certainty," Hinchcliffe said.
"No one wanted to see Junee not continue in the Group so now they have the opportunity to progress and it's going to be good going forward."
No club voted against Junee's return to first grade.
However they did strike down plans to retain a full home and away draw.
Instead a 16-round season has been introduced with the season to begin on April 23.
The grand final will be played on September 18.
Group Nine welcomed Tim Humphries onto the board however there are three vacancies with former chairman Peter McDermott, vice-chairman Ian Close and Lisa Crick all stepping down.
Bernie Delaney is the new vice-chairman and it is hoped the empty positions can be filled before the start of the season.
The concept to introduce a 'Magic Round' wasn't supported by clubs however a new challenge cup will be introduced.
Teams will have the ability to challenge the holders, for a fee, if drawn to play them in their next home game.
Temora, who have the bye to start the season, was drawn out to be the first holder.
Hinchcliffe hopes it can add another aspect to the season.
"We're hoping it brings something different, with a slightly new view and hopefully some excitement," he said.
