Father Paddy Sykes united a couple in their late twenties on Saturday at Saint Michael's Cathedral, with a total turnout of 25 people.

While the crowd was smaller than they had originally hoped, the amount of people helping celebrate the occasion was anything but small.

"They live streamed the ceremony so their friends and family in Victoria, and those overseas, could watch it all still in real time," she said.

"I only heard positive feedback from everyone involved, and about how much they enjoyed it."

While COVID-19, hopefully, won't last forever, Fr Sykes said he could see the live streaming of weddings becoming commonplace.

"I really think it's going to become standard," he said.

"Take elderly grandparents, for example, who may be in nursing homes and would not ordinarily be able to make it - live streaming means they don't have to wait ages down the track to see photos, they can actually watch it as it happens."

Wedding celebrants' roles in couples' special days have become all the more valued with the limited number of guests allowed to share the experience with, and Fr Sykes said he was thrilled to be involved.

"It was a very special day and it was nice to be back in the Cathedral," he said.
