The works are the first stage of a major upgrade under Flynns Beach Master Plan and is a $2.5 million investment in the area.

Council funded $1.3 million of the works while a further $1.2 million was contributed under the NSW Government's 2015/16 Coastal Management program.

The upgrades include a new vertical seawall, beach access stairs and improved parking, including two disabled parking spots.

There is a new accessible pedestrian and vehicle ramp, a two-metre wide footpath, refurbished shower area and beach access point.

These improvements complement the ongoing upgrades to the Coastal Walk, and improve the safety, accessibility and overall appeal of this popular destination.

Mayor Peta Pinson said it was great to see the community enjoying the area.

"We are so lucky to have an enviable array of choices from which to enjoy our coastline, and Flynns Beach has definitely moved to the top of the must-do list," Cr Pinson said.

"The construction work has been delivered in an extremely efficient manner, and I'd really like to thank the local businesses for their support and understanding, and we all look forward to the benefits these improvements will bring for many years to come."

Member for Port Macquarie, Leslie Williams Flynns Beach is a popular local beach and to now have this new seawall and improved beach access is an achievement.

"It is also another fine example of what can be achieved with council and the NSW government working together to deliver vital infrastructure for our local community, including the upgrades to Charlie Uptin Walk, the multi-million redevelopment of the Stuart Park Sporting Precinct, the construction of new footpaths at Telegraph Point and the new toilet block in Short Street, just to name a few," Mrs Williams said.

The next stages of the Flynns Beach Master Plan will include new picnic and barbecue facilities, a new children's playground, improved parking facilities, pedestrian linkages and parkland development.
