While the Holy trinity Church at Kameruka may only hold one service each year, people come from far and wide for the experience.

Designed by architect Edmund Blackett, and built in 1869 by Charles Galli of Wolumla and volunteer labour from the Sir Robert Lucas-Tooth owned estate, the church and the cemetery were later donated to the Anglican Church.

It was one of the first churches built on the South Coast after the British colonisation of Australia.

The anniversary service will be held on Saturday, November 23, and will host visitors including Bishop Mark Short of the Arch Diocese of Canberra and Goulburn, and Reverend Lou Oakes of the Sapphire Coast Anglican Parish who will both provide sermons.

Invitations have been sent out to past and current parishioners from as far as Tasmania.

Warden for both Candelo and Kameruka churches Max Thompson said some past clergy may also be in attendance.

"Friends of Holy Trinity is a group started by Sandy McQueen around five years ago to keep a network going to help fund maintenance and restoration projects," Mr Thompson said.

"The annual service is always good because the church is always packed."

In 2016 a visitor left the doors open, allowing swallows to enter the church and over time destroyed much of the historic brassware inside.

Silversmiths WJ Sanders from Marrickville in Sydney have restored the brassware after polishing failed to do the job.

Mr Thompson said the church is appealing for donations to contribute to the restoration work.

Following the 150^th birthday celebrations there will be an open inspection of the Kameruka Estate homestead gardens, and a picnic beside the historic Lords View Oval.

"I would like to give a special mention to the continued generosity of Barry Moffitt, of Kameruka Estate, for his support of the church and Kameruka grounds for this historic occasion," Mr Thompson said.
