If your church's Facebook or Instagram feels quiet, the instinct is to post more. This article looks at whether frequency is actually what helps, using the closest Australian data available, and what to focus on instead if it isn't. It doesn't cover platform-by-platform algorithm mechanics, those change too often to be worth pinning to a page like this.
What the data actually shows
There's no Australian study measuring exactly how often churches or charities should post. But Infoxchange's 2025 survey of 824 Australian not-for-profits found only 36 percent are confident their social media presence delivers real value, regardless of how much effort goes in. Facebook remains the platform almost all of them use, 87 percent, with Instagram now a strong second, 53 percent, up sharply over the past decade.

That's worth sitting with before changing anything. Most Australian not-for-profits, not just churches, aren't confident their social media is working. That's not a sign you're doing something wrong. It's the normal experience of running an account with no marketing budget and no one whose job it actually is.
What actually helps
Church Support Australia's own look at Facebook Pages found organic reach sits at roughly 1 to 2 percent of followers per post, and posting more often doesn't meaningfully change that. What does more work is a complete, current profile: the right address, service times, and a post from the last few weeks, since that's what shows up when someone searches your church by name before they visit. See Facebook for Churches for the full picture on what a church Page is actually for.
A rhythm you can sustain
If frequency isn't the fix, the practical answer is smaller than it feels. Once a week, on a day you can actually keep, is enough to keep a profile looking current. A sustainable weekly post beats a burst of five posts in one keen week followed by a month of silence, both for how the Page reads to a visitor and for whoever's doing the writing.
If the harder part is knowing what to post rather than when, Social Media Captions for Church Services has a working set of categories to pull from.
