More than 500 submissions have been made on a $1.1 million plan to extend Soldiers Point Marina.
The exhibition period for the project closed on Saturday following a four-week extension to the original timeframe.
The Newcastle Herald has reported the proposal would extend the marina by 58 berths and introduce a valet parking service to the area.
The Joint Regional Planning Panel will make a final decision on the project's fate after Port Stephens Council planners assess the project and submissions.
A Port Stephens Council spokeswoman said staff were sifting through about 550 submissions yesterday, which included a number of form letters.
"All submissions will be treated as individual and will be responded to by council staff," she said.
"The council will need to now make the appropriate assessments, which may require further investigation or information from the applicant, before being in a position to make a recommendation to the [panel]."
The majority of the submissions were understood to oppose the marina extension.
Soldiers Point Community Group chairman Colin Howard said opposition to the plan was multifaceted, and his group was committed to fighting the project as it stood.
"There's a mix of business, environment and social reasons [for opposing the plans] that have come back," Mr Howard said.
The planning panel and council staff will meet on Thursday to discuss the key elements of the application.
