NAVY helicopters will roar over the Sunshine Coast during the 2017 Freedom of Entry involving the Sunshine Coast Council and Royal Australian Navy.

Held once every four years, the event will take place in Caloundra this Saturday during which council and the Navy will renew the Freedom of Entry rights and their Friendship Agreement.

Mayor Mark Jamieson said the 816 Squadron of the RAN's Freedom of Entry ceremonial march and challenge, in full military regalia, recognised a mutual dependency between the military and the community.

"This year marks the 21st anniversary of 816 Squadron's acceptance of the right to exercise Freedom of Entry to the city of Caloundra," Cr Jamieson said.

"The Freedom of Entry is the most honourable distinction a city can bestow on a contingent of the Australian Airforce.

"We cherish the relationship that has grown between the Sunshine Coast, and Caloundra in particular, and the 816 Squadron."

The celebrations will kick off at 10am with a Navy Band march through Kings Beach and Navy Seahawk helicopter flyovers. 

The 816 Squadron operates 16 Sikorsky S-70B-2 Seahawk helicopters with the primary role to provide anti-submarine warfare and anti-surface surveillance.

816 Squadron Commanding Officer Anthony Savage said the squadron had a unique history with Caloundra.

"In 1996, they participated in training exercises in Moreton Bay, during which time retired members of the Fleet Air Arm living on the Coast initiated introductions between the squadron and the former Caloundra City Council," Commander Savage said.

"As a result, Caloundra City Council first bestowed Freedom of Entry rights in 1996.

"The squadron has exercised its right to march into Caloundra on several occasions since.

"They also maintain close ties with Caloundra through attending annual Anzac Day celebrations."
