Australia Meta Ads Reach Estimates: Broad and Segments 2026
Data source for audience estimates in Australia
The data was retrieved via the Meta Marketing API and may differ from the audience forecast shown in Ads Manager. The tables reflect the minimum available audience estimate for Advantage Placements, with no overlap with any additional targeting layers.
These figures are useful for planning technical reach (how many accounts can potentially be reached). In practice, this type of estimate is often directionally comparable to the Reach you see in the ad account, but converting “users” into an estimate of real people (not accounts) requires separate calibration and transformation.
