Central Coast's treble-winning coach Mark Jackson has re-signed for three years as he attempts to turn the Mariners' recent success into an A-League Men dynasty.

Jackson had the daunting task of following in the footsteps of championship winner Nick Montgomery when he joined ahead of last season.

The Englishman led the Mariners to the ALM premiership-championship double plus the AFC Cup in his first year at the helm and was named coach of the year.

Jackson and assistant Danny Schofield have both signed until 2027 as they chase further success, including an ALM three-peat and competing in the Asian Champions League Elite.

"I am delighted to be able to extend my time here on the Central Coast alongside Danny Schofield," Jackson said.

"We had a clear vision of what we wanted to achieve when we arrived, we worked extremely hard with the rest of the staff to achieve that last season and we want to continue to build on that

"We want to continue to develop the players and team to be a club that everyone on the Coast can be proud of.

"We did that last season, giving the fans a lot to cheer about, and it is our job to do that again.

"I am really pleased to be staying with this great football club, I am extremely thankful for the support that the chairman Rich Peil and Simmo (Matt Simon) gave us last season in everything that we did, and the trust shown by them in me to lead this team forward in the years to come."

Assistant Schofield famously couldn't coach in the grand final after being sent off and then flipping the middle finger at TV cameras in the Mariners' semi-final win over Sydney FC.

Mariners sporting director Matt Simon welcomed the new contracts for both coaches.

"We are delighted to be able to extend Jacko and Danny's contract and give them new deals with us at the Mariners," Simon said.

"What the pair did last season in their first campaign in charge, not only with the success that they achieved on the pitch leading us to the treble, but also the culture that they brought, was incredible.

"Both of their characters and work ethic align perfectly to who we are as a club, and it is really exciting to have them continue with us to grow not only the first team but the Mariners as a whole."

Under Jackson, the Mariners have recorded just six losses from 42 games while still developing talented local players
