Financial data as at June 2025. Sourced from Charities Services register.
Charities Services Tier 3 reporting allows charities under $2M revenue to file a simple-format annual return rather than audited financial statements. The return reports totals but not the program/administration split or the line-item detail our template needs. No red flags were detected in what was filed, and revenue is below the $2M Tier 2 boundary where audited accounts become mandatory. A letter grade is withheld rather than assigning one that would be driven by the template-fit, not the charity's operations. The charity's filed figures are shown above, and any structural concerns a donor would want to look at are surfaced separately. (v3.3 — aligned with Charities Services tier boundary; matches Charity Navigator and CharityWatch US practice.)
