That's 25 bands of tireless volunteers visiting the sick, caring for the elderly, running soup kitchens and welcoming refugees.
And the list goes on.
But if you didn't know this, don't feel (too) guilty.
Despite boasting a vast and vibrant parish, the work of St Mary's quiet achievers can often fly under the radar.
Which is why the church will be holding a parish expo this weekend to celebrate and raise awareness of all they do in the community.
“We have a lot of people who identify as part of the parish but have a limited understanding of all that goes on in the parish beyond mass,” St Mary's pastoral associate Christine Sebire said.
“We have two schools that are a part of the Catholic community, but who can be unaware of the different ministry groups we run.”
The expo will feature stands with information about each of the ministries.
“It will be a chance for people to walk around and go, ‘wow, I didn't know I could be involved in all this’," Ms Sebire said.
“We also encourage members of the broader community to drop in and take a look.
“There are so many different ways for people to get involved, it's all about people using their gifts.
“So they can do anything from gardening and cleaning the church to being a part of the music team or baptism preparation. There's a whole gamut of ministries.”
The church will also unveil its new strategic plan and brand at the expo, which have been in the works for months and kept strictly under wraps until the big day.
The parish expo will be this Sunday, kicking off with a mass at 10am – there will only be one mass on the day as opposed to the traditional three masses.
Following the mass, everyone will be invited to the expo at 11am.
