His service begins at 8:30am, when the congregation — comprising a single parishioner — arrives at the 118-year-old All Saints Anglican church.
Bruna Robinson, who has attended Sunday mass at Briagolong for 28 years, enjoys discussing the lessons of faith with Reverend Perryman, comforted by the notion that someone cares for her in the face of life's challenges.
She recalls when the church, now slightly dishevelled with cobwebs and abandoned Christmas ornaments, was once a gathering place for the local community.
"We had playgroup, community health sessions. We would sit and knit and crochet, or just chat as a social gathering."
But now, she's the lone and soon-to-be last parishioner at All Saints, which was recently marked for closure.
Mobile ministry
Reverend Perryman delivers two ceremonies each Sunday — an 8:30am service in Briagolong or Munro on alternating weekends, followed by a main service in Stratford, which is live-streamed and attracts viewers from interstate, overseas and a local nursing home.
But it's a race to get from one service to the next.
"It is a bit of a mad dash, and it makes it really difficult when you are just offering that ministry and that worship and then you're running off down the road," he said.
The Parish of Avon, comprised of Stratford, Munro, Briagolong and the Dargo district, once included the Dargo church, which closed in 2012.
At St Mary's in Munro, built in 1922, anywhere from four to seven parishioners can attend a service.
As church buildings age and maintenance falls behind schedule, Reverend Perryman and his volunteer team contend with everything from possums to spiders, gum leaves, fallen branches and storm damage.
"There is recognition that a lot of these beautiful buildings do take a lot to maintain, and not just in terms of bricks and mortar, but the grounds as well," he said.
For Elizabeth Bates, who has attended the Munro service on and off for 50 years, preserving the Munro church is about preserving town infrastructure, legacy and identity.
"The people who built this church and the families that I've know who've passed away now, they worked so hard to build the Christian faith in this community for us, and I just want to enjoy it," she said.
"I really miss the intimacy, the feeling of worship with a group of people.
"It's not the same on social media as it is to come here. It's something that is really important in my life. It gives me strength."
The dilemma of aging, under-utilised buildings is forcing the Anglican church to think creatively about finding new ways to deliver services.
With the forthcoming sale of the Briagolong church, a less formal incarnation of the Briagolong service has already been trialled at the Briagolong Community House, attracting a gathering of about seven people.
"The church building may shut, but the church is still gathering," Reverend Perryman said.
New pathways forged
At Holy Trinity in Stratford, established in 1868, children run around a kindergarten table beside a lectern, as Reverend Perryman rushes through the back entrance to tune his guitar and rehydrate for the 10am service.
"We do try and offer a bit of everything for everyone," he said.
The church has merged a free-range Sunday school, craft, live music and audio-visual projections with the more formal, traditional elements of a service.
As life becomes more financially and socially difficult for people, in an era where stripped-back social interactions have become the norm, Reverend Perryman's inclusive philosophy extends to a vibrant calendar of parish-organised activities.
From music for young children and parents to family movie nights, men's breakfasts, fundraising raffles, dinners, the annual church fete and Blessing of the Pets, low-cost opportunities for social connection extend to the broader community.
"I'm very thankful that I don't run this race alone," Reverend Perryman said.
"Anything that we do here or out in the community is only made possible because of our wonderful volunteers."
But with limited funds, eroding infrastructure and an aging population, Reverend Perryman believes fresh perspectives and creative thinking are critical for the long-term sustainability and relevance of regional parishes.
"At some point … the conversation has to change from just trying to do 'more with less', to actually trying to be strategic in how we approach this from a different direction," he said.
"We need to find an out-of-the-box way of doing ministry and being a church."
