Central Coast Stadium opened in 2000 and has remained relatively untouched ever since, with the club devising a five stage concept to ensure it can facilitate a variety of football matches and be in contention to host concerts.
The stadium upgrade and concept will also include dual big screens, a state of the art sound system and a hotel with views of the Brisbane Water.
The Mariners will use their next home A-League game against Perth Glory on January 28 to continue to grow the vision, with fans formally invited to present their ideas on matchday.
"As the Central Coast Mariners continue to grow, Central Coast Stadium must grow with us," Mariners CEO Shaun Mielekamp said.
"Unfortunately, in the last 17 years the only thing that has changed at the stadium is the height of the palm trees.
"The worst thing that can happen is nothing. Our main priority is to drive change and growth. If the Mariners aren’t going to do it, then who is?"
Central Coast are currently sitting in ninth on the A-League table, two wins behind Newcastle Jets in the top six.
