Executive Summary
This report analyses community-submitted telecommunications safety data across Western Australia between 1–30 September 2025. All classifications, trend observations, and regional patterns are derived from first-hand community intelligence aggregated through the Reverseau platform.
Western Australia recorded 390 community reports across 309 unique phone numbers during the reporting period. Compared to August 2025, reporting volume showed relatively stable levels, while 309 numbers remained under active community monitoring throughout the month.
Scam remains the most frequently assigned community classification at 29% of categorised reports, with a scam classification ratio of 29% across all submissions. Scam maintained its position as the dominant classification in both periods, suggesting sustained targeting patterns rather than campaign rotation.
Geographically, reporting activity was concentrated in Perth, followed by Fremantle and Pinjarra. Perth recorded more than double the reporting volume of the next most active locality (Fremantle), indicating concentrated campaign activity or higher community engagement within this area.
September often marks the beginning of delivery and parcel scam escalation as online shopping activity increases ahead of the holiday retail period.
Scam classifications account for 29% 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 WA data dashboard for real-time classification and trend data.
Why This Matters
While scam classifications represent a smaller share of overall reporting at 29%, the diversity of classification categories observed across Western Australia underscores the importance of community-driven monitoring. Telecommunications safety extends beyond scam detection — nuisance, telemarketing, and unknown classifications each contribute to a more complete picture of how phone numbers interact with the community. Continued reporting across all categories strengthens the analytical foundation that powers early detection and trend visibility.
Scam Category Breakdown
Community classification distribution across WA for the period 1–30 September 2025. Classifications are assigned by reporting users based on their direct experience with each number.
Scam accounted for 29% of categorised reports during September 2025. In August 2025, Scam held the top position with 33% of classifications. Scam maintained its position as the dominant classification in both periods, suggesting sustained targeting patterns rather than campaign rotation.

Month-to-Month Comparison
Compared to August 2025, Western Australia experienced relatively stable levels in community reporting volume. Overall activity has decreased, with substantial monitoring coverage across the state.
Seasonal Context
September often marks the beginning of delivery and parcel scam escalation as online shopping activity increases ahead of the holiday retail period. The relatively stable reporting volume suggests consistent campaign activity and community engagement levels between the two periods.
Classification Movement
Scam classifications accounted for 29% of categorised reports in September, with scam-specific reports representing 29% 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
Reporting distribution across Western Australia localities remained broadly consistent with prior periods, with Perth continuing as the primary reporting centre.
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 WA accumulated multiple community reports within a compressed time window during 1–30 September 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 4 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 WA. 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 September 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 Western 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 1–30 September 2025. All data is aggregated and anonymised before publication.
- Source: First-hand community reports submitted via Reverseau.
- Scope: Numbers with a registered allocation within Western Australia (WA).
- Period: 1–30 September 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.
