The Archdiocese of Perth will mark a significant milestone in 2025 as Holy Trinity Catholic Church on Rottnest Island celebrates its 50th anniversary.

The Golden Jubilee will be held on Sunday, 15 June, with a Thanksgiving Mass at 10.00am led by Vicar General, the Very Rev Monsignor Vincent Glynn.

The occasion will also include the blessing of a newly commissioned Golden Memorial Plaque, followed by a celebratory social gathering and high tea in the church courtyard.

Holy Trinity Church stands as a tribute to the enduring faith of Perth Catholics and the visionary work of its founder, the late Monsignor Sean “Mons” O’Shea.

First arriving on the island in 1961—mistakenly believing he was heading to Garden Island—Monsignor O’Shea became a beloved spiritual figure, frequently returning to celebrate Mass in makeshift venues like the island’s picture theatre.

By 1975, Monsignor’s dream of a dedicated place of worship became reality, thanks to the support of then Archbishop Lancelot Goody, local board member Des Sullivan, and architect C.J. Gabriels.

The church’s distinctive ochre façade, movable side doors, and adjoining priest’s quarters reflect a style both functional and welcoming. The structure remains almost entirely unchanged today.

Perhaps most memorable is the church’s carillon of bells, installed in 1985.

Without a crane on the island, Monsignor O’Shea famously arranged for the US Navy’s Pacific Fleet to airlift the bells by helicopter—a feat emblematic of his spirited determination.

Throughout his ministry, Mons O’Shea’s hospitality became as famous as his homilies.

He was known for welcoming guests with pikelets and fig jam, his signature gesture of friendship and faith.

Even after suffering two strokes, he continued his ministry until his retirement in 2012. He passed away later that year and is buried in the church courtyard, a few steps from the altar he served so faithfully.

Current Chaplain, Fr Joseph Rathnaraj, is encouraging all Catholics across the Archdiocese—along with visitors and admirers of Rottnest Island—to attend the Jubilee celebrations.

“This is a time to honour Monsignor O’Shea’s legacy and give thanks for fifty years of ministry, prayer, and peace shared here on the island,” Fr Joseph said.

With Holy Trinity continuing to welcome both regular worshippers and curious travellers each Sunday, the Golden Jubilee serves as a reminder of the Church’s timeless role in offering sanctuary and spiritual nourishment.

For Perth Catholics, the event presents a meaningful opportunity to reconnect with the island’s rich pastoral heritage and be part of a once-in-a-generation celebration of faith and community.

Ferry services will be available from Fremantle and Hillarys, and early bookings are recommended. All are welcome to join in this special day of remembrance and renewal.
