Parish's management are understood to be pressing for a six-year extension at Tullamarine, a stance that is reportedly creating a standstill, given Essendon aren't willing to offer a contract longer than five seasons.
Further stipulations in regard to the unsettled AFL collective bargaining agreement and the influence it could have on new contracts are also said to be a factor in negotiations.
Parish has a reported suitor in Geelong, with the Cats understood to be looking toward the Winchelsea native as a target through free agency.
With Essendon's season now over after a disappointing conclusion to Brad Scott's first season as senior coach, Parish will soon inform the club of his intentions for the future - if he hasn't already - as exit interviews were scheduled this week.
But despite the uncertainty around where he could be playing in 2024, Parish has looked to reassure Essendon fans that he hopes to be donning the sash next year. Speaking to 9 News Melbourne, the 26-year-old said an agreement could be made soon.
"My manager and the club have had some great discussions, especially the last few days since the season has been done and dusted," Parish said.
"We're in a great position, hopefully it's all over and done with pretty soon.
"Absolutely (I'm keen to re-sign), I've been committed to this club as soon as I walked in the door and I'm still committed to this day.
"I've got a great relationship with Scotty, the coaches and my teammates. There was a little hiccup in the road as it wasn't the way we wanted to end the year, especially with where we put ourselves in a great position to play finals. We've still got plenty of work to do."
Essendon, who delisted three players on Monday, have a string of key players still unsigned as they enter the off-season, with forward pair Harrison Jones and Jye Menzie, defensive duo Brandon Zerk-Thatcher and Kaine Baldwin, and youngster Massimo D'Ambrosio, among others, yet to recommit to the club.
Zerk-Thatcher is understood to be eager for a move to Port Adelaide this off-season as he ponders a move back to his home state.
