District League promotion play-off winners Bellambi have applied to make the jump into the Illawarra Premier League for the 2014 season.
The Rosellas put forward their case to Football South Coast this week to make the move into the top division.
The governing body will review the bid throughout October.
Bellambi were one of the dominant forces in the District League during 2013 - they secured the League title with a win over Warilla then defeated Helensburgh Thistle in the two-leg promotion play-off 5-1.
This on-field dominance convinced club officials and players to take the plunge and play in the Premier League.
"As a sporting club we always want to strive to play at the top level and the coaches and senior staff agreed that would be our direction pending the players commitment," Bellambi club president Joshua Dodd said.
"The consensus was the majority of the players in the core group want to play at the highest level as well.
"It was obviously quite a big decision as it is for any club who are going to make the step from District League to Premier League."
The step up in divisions will require Bellambi to drop their reserve grade side and provide adequate financial backing for the top grade.
"The sponsors are a big thing because financially it is obviously a big step up to Premier League," Dodd said.
"We have to make sure we not only can compete but can compete with the bank account as well.
"Funding is important. Some local businesses - like Touleng Services and the Illawarra Denture Clinic - they are all backing us."
Funding would also allow the Rosellas to recruit new talent but Dodd insists there wouldn't be a complete overhaul of the squad if they made the jump.
"One of the biggest points as a club, and we know from past clubs who have done it - one of the worst things you can do is strip the club back bare and start with fresh players," Dodd said.
"I assure people it is not our angle.
"We understand we have to strengthen our playing group.
"We are actively seeking a handful of players but essentially the core group of players who have been playing District League will be expected to play, and improve, in the Premier League."
If the Rosellas were to be promoted, they would become the fourth club in the Northern Suburbs to join the top grade. Woonona made the shift last season.
A verdict is due to be made in the last week of October.
