Most small Australian churches have a Facebook Page. Someone volunteers to manage it, usually alongside a dozen other jobs. The honest question in 2026 is what the Page actually does for a church, and what managing it requires in terms of privacy and child safety under current Australian law.
This article covers the public Page and any member Group your church runs. It does not cover Facebook advertising, Instagram, or internal team messaging.
This article was last verified in July 2026. Privacy law and platform policies change. Check the current position with the Office of the Australian Information Commissioner and the eSafety Commissioner before you act on what you read here.
What your Page actually does
The short answer is less than many church admins expect, and that is worth knowing clearly.
Organic reach (the percentage of followers who see a given post without paid promotion) averages between 1% and 2% globally across organisations of all kinds. No Australian-specific breakdown is published, but there is no reason to think church Pages perform differently. A church with 200 followers typically reaches 2 to 4 people per post.
That figure is not a reason to abandon the Page. It is a reason to be clear about what the Page is for.
A complete, up-to-date Facebook Page is indexed by Google. When someone searches your church by name, or searches "churches in [suburb]," Facebook Page data surfaces alongside other local results: address, service times, phone number, recent activity. The primary value of a church Facebook Page is search-and-confirm: people check it before they visit, not because they see your posts in their feed.
The practical job is to keep the Page complete and current. That means a current address, service times, phone number, cover photo, and a post from the last few weeks. Posting frequency has little effect on how many people see each post. A complete Facebook Page also reinforces your Google Business Profile listing, though it is not a substitute for one.
Events are the best free tool you have
Regular Page posts reach only a fraction of your existing followers. Facebook Events work differently.
Events created on a church Page surface in Facebook's local Events discovery tab, visible to people who do not follow the Page at all. This is one of the few remaining ways a small church can reach potential new visitors on Facebook without spending money.
A recurring Sunday service Event is the simplest starting point. Add Events for community activities, Easter and Christmas services, or anything else open to the public. When a member shares an Event to their own profile, it extends reach without any extra effort from the admin.
If you have a Group, the rules have changed
A private Facebook Group for existing members tends to work better for two-way engagement than Page posts. The algorithm treats Group content more like personal posts, so prayer requests, announcements, and event discussion are more likely to be seen by members who actually want to see them.
Two legal developments since 2025 change what running a Group requires.
Under-16s cannot be Facebook members. From 10 December 2025, Facebook is a designated age-restricted social media platform under Part 4A of the Online Safety Act 2021 (Cth). Meta is required to take reasonable steps to prevent people under 16 from holding accounts. A church Facebook Group is not an appropriate channel for youth participants under 16. Use email or a parent-mediated WhatsApp group for under-16 pastoral contact. The eSafety Commissioner has current information on how the age restriction framework operates.
Posting identifiable photos of children on a public Facebook Page without written parental consent creates real legal risk. The Privacy Act 1988 (Cth), Schedule 2, which commenced on 10 June 2025, introduced a statutory tort for serious invasions of privacy. It applies to all entities, including churches below the small-business exemption threshold. A photo of a child posted publicly without consent could satisfy the elements of the tort. The Office of the Australian Information Commissioner publishes guidance on posting photos and videos written for organisations.
A two-adult admin minimum applies to any Group that includes minors, consistent with electronic communication practice in safe-ministry contexts. Make sure your Group is set to Private, not Closed. Facebook phased out the Closed setting some years ago, but older Groups may still display the label. Churches without a denominational safe-ministry policy can use the National Principles for Child Safe Organisations as a baseline.
