Executive Summary
This report analyses community-submitted telecommunications safety data across South Australia between 1–31 August 2025. All classifications, trend observations, and regional patterns are derived from first-hand community intelligence aggregated through the Reverseau platform.
South Australia recorded 225 community reports across 160 unique phone numbers during the reporting period. Compared to July 2025, reporting volume showed a notable decrease of 47%, while 160 numbers remained under active community monitoring throughout the month.
Scam remains the most frequently assigned community classification at 32% of categorised reports, with a scam classification ratio of 32% across all submissions. A classification shift was observed: Scam displaced Legit as the dominant category, which may indicate a transition in active campaign strategies or a change in community reporting behaviour.
Geographically, reporting activity was concentrated in Adelaide, followed by Alford and Ceduna. Adelaide recorded more than double the reporting volume of the next most active locality (Alford), indicating concentrated campaign activity or higher community engagement within this area.
August represents a mid-year baseline period. Reporting volumes tend to stabilise, though emerging campaign types may begin to surface ahead of the holiday season.
Scam classifications account for 32% of reports, suggesting a mixed telecommunications activity landscape where non-scam reporting categories play a significant role in the overall safety picture. Residents are encouraged to report suspicious telecommunications activity and consult the SA data dashboard for real-time classification and trend data.
Why This Matters
The proportion of scam-classified reports at 32% indicates active but evolving targeting patterns across South Australia. Understanding these patterns at a community level enables faster identification of emerging campaign types and reduces the window between first contact and community-wide awareness. Sustained reporting activity across multiple localities strengthens the collective intelligence foundation, allowing classification convergence to accelerate as more residents contribute first-hand safety data to the SA reporting ecosystem.
Scam Category Breakdown
Community classification distribution across SA for the period 1–31 August 2025. Classifications are assigned by reporting users based on their direct experience with each number.
Scam accounted for 32% of categorised reports during August 2025. In July 2025, Legit held the top position with 28% of classifications. A classification shift was observed: Scam displaced Legit as the dominant category, which may indicate a transition in active campaign strategies or a change in community reporting behaviour.

Month-to-Month Comparison
Compared to July 2025, South Australia experienced a notable decrease of 47% in community reporting volume. Overall activity has decreased, with substantial monitoring coverage across the state.
Seasonal Context
August represents a mid-year baseline period. Reporting volumes tend to stabilise, though emerging campaign types may begin to surface ahead of the holiday season. The observed decrease of 47% may reflect seasonal reporting variation, reduced campaign activity, or shifts in community engagement patterns during this period.
Classification Movement
Scam classifications accounted for 32% of categorised reports in August, with scam-specific reports representing 32% of all submissions. These shifts in community classification patterns may reflect evolving campaign tactics, changes in the types of numbers being reported, or natural variation in reporting behaviour between periods. Monitoring classification movement over consecutive months provides a more reliable indicator of genuine trend shifts than any single-month comparison.
Regional Variation
Adelaide maintained its position as the most active reporting locality even as overall volumes declined. This persistence suggests that reporting behaviour in metropolitan areas is more resilient to volume fluctuations than regional submissions.
Service Type Distribution
Local Service numbers account for 100% of reported activity, reflecting the broader national pattern where mobile-originated calls dominate community safety reports. Residents should exercise particular caution with unsolicited calls from unfamiliar local service numbers.
Emerging Trends & Observations
Several numbers exhibited accelerated reporting velocity within compressed time windows, followed by classification convergence toward scam designation.
Rapid Accumulation Signals
10 numbers within SA accumulated multiple community reports within a compressed time window during 1–31 August 2025. This velocity pattern is consistent with active call campaigns or coordinated targeting activity. Numbers exhibiting rapid report accumulation frequently transition from initial “Unknown” or “Suspicious” classifications to confirmed “Scam” designation within days.
Flagged numbers averaged 5 reports each, consistent with early-stage campaign detection where community awareness is still building.
Several flagged numbers exhibited cross-locality reporting dispersion, with community submissions originating from multiple areas within SA. This pattern suggests broadcast-style outbound activity rather than localised outreach, consistent with automated dialling campaigns that target numbers across geographic boundaries.
Divergent Classification Signals
Several numbers display mixed community classifications — receiving both scam and non-scam reports during August 2025. This divergence may indicate numbers transitioning between legitimate and illegitimate use, caller ID spoofing of legitimate business numbers, or community uncertainty about the nature of calls received. Numbers with divergent classifications warrant continued monitoring as community consensus develops.
Community Safety Guidance
- Do not return missed calls from unknown 08 numbers without verification.
- Verify any government agency claims through official websites or published contact numbers — the ATO, Centrelink, and Medicare will never threaten immediate action via phone.
- Avoid clicking payment or delivery links received via SMS from unrecognised senders.
- Report suspicious telecommunications activity to help build community safety intelligence for South Australia.
- Check numbers on Reverseau before returning calls from unknown sources.
Data Methodology
This report is compiled from community-submitted telecommunications safety reports for the period 1–31 August 2025. All data is aggregated and anonymised before publication.
- Source: First-hand community reports submitted via Reverseau.
- Scope: Numbers with a registered allocation within South Australia (SA).
- Period: 1–31 August 2025 (calendar month).
- Classifications: Assigned by reporting users based on their direct experience.
- Limitations: Data reflects community perception, not verified telecommunications records. Reporting volumes are influenced by platform adoption and user engagement patterns.
