Overall audience size
According to the minimum audience estimate in Pinterest Ad Account, Pinterest’s potential ad audience in Australia (18+) totals 3,944,000 users. This is the estimated audience available for advertising reach within the platform, broken down by age and gender category.
The largest single age segment is 25–34, with 1,290,000 users. The next largest group is 18–24, with 1,090,000 users. Together, these two cohorts form the core of Pinterest’s estimated ad audience in Australia and account for just over three fifths of the total volume shown in this dataset.
This points to a younger adult audience profile overall. At the same time, Australia’s distribution is not limited only to the youngest users, since older groups still contribute meaningful scale within the platform’s total estimated reach.
Age structure of the audience
The age breakdown shows that Pinterest’s estimated ad audience in Australia is concentrated most heavily in the 18–34 range. These groups make up 2,380,000 users, or about 60.3% of the total audience available through Pinterest Ad Account.
- 25–34: 1,290,000 users, or about 32.7% of the total
- 18–24: 1,090,000 users, or about 27.6%
- 35–44: 605,000 users, or about 15.3%
- 55+: 571,000 users, or about 14.5%
- 45–54: 388,000 users, or about 9.8%
The 25–34 segment stands out as the dominant age cohort in Australia’s Pinterest audience profile. It leads clearly over 18–24, making it the single most important age group for understanding platform scale in this market.
At the same time, the older audience remains visible in a way that makes Australia more balanced than markets where the platform’s reach thins rapidly after age 34. The 55+ group, at 571,000 users, is only slightly smaller than 35–44 and noticeably larger than 45–54. This suggests a younger core audience, but not an exclusively youth-driven structure.
Overall, Pinterest’s ad audience in Australia can be described as young-adult oriented, with the strongest concentration in 25–34 and a still meaningful older audience, especially in the 55+ group.
Gender structure: strong female dominance
The gender split in Australia’s Pinterest Ad Account data is clearly weighted toward female users. The Female audience totals 2,847,000 users, which is about 72.2% of the total estimated audience.
For comparison, the Male audience totals 826,000 users, or about 20.9%, while Not Set accounts for 271,000 users, or about 6.9%.
This means female users account for well over two thirds of Pinterest’s estimated ad audience in Australia. The female lead is not limited to a single age band. Across every age group in the dataset, female audience size is larger than male audience size, making this a structural feature of the platform’s demographic profile.
The largest female segments appear in 25–34 (921,000) and 18–24 (807,000), which also correspond to the two largest age cohorts overall. That alignment suggests that Pinterest’s scale in Australia is driven primarily by women, especially in the platform’s younger adult segments.
The Not Set category as a distinct segment
The Not Set category totals 271,000 users in Australia. This is not a marginal number and should not be ignored when interpreting the demographic structure of Pinterest’s estimated ad audience.
The biggest Not Set concentration appears in 25–34 (83,000), followed by 18–24 (62,000), 35–44 (49,000), 55+ (45,000), and 45–54 (32,000).
While most of the audience is still concentrated in the Female and Male categories, Not Set remains a visible third segment. In a market of this size, that category is large enough to matter in campaign planning, reporting, and any analysis that relies on gender-based audience splits.
Conclusion
Based on the minimum audience estimate available in Pinterest Ad Account, Pinterest’s estimated ad audience in Australia (18+) totals 3,944,000 users. The audience is concentrated most heavily in the 18–34 range, which accounts for about 60.3% of the total, with 25–34 standing out as the largest single age segment at 1,290,000 users.
The gender profile is strongly led by Female users, who represent 2,847,000 people, or about 72.2% of the total. The Male audience totals 826,000, while Not Set accounts for 271,000 users.
Overall, Pinterest Ads in Australia appear to be centered on a younger adult audience with a clearly dominant female segment, while still maintaining a meaningful older audience and a visible Not Set category within the broader demographic structure.
