Research Centre Impersonation Reports for 03 8804 5818

Fifteen contributors have flagged calls from 03 8804 5818 (also written as 0388045818) for suspicious activity centred on fake research centre impersonation. Several reports describe callers claiming affiliation with Australian research organisations, asking demographic questions about cost of living, and dangling cash prizes or competition entries as incentives to participate. The pattern is consistent across reports: contributors either avoid answering or experience hang-ups and disconnections shortly after providing personal information like age.

A distinctive feature of calls from 0388045818 involves the number becoming non-operational when contributors attempt callback verification. Multiple contributors report trying to call back within minutes and receiving "number is no longer in service" messages, suggesting the use of disposable or spoofed numbering rather than a legitimate business line.

What Callers from 03 8804 5818 Claim

Contributors report callers identifying themselves as representatives from an "Australian research centre" conducting cost-of-living surveys. One contributor described an automated voice claiming research affiliation and mentioning eligibility for cash prize drawings. The opening is typically casual, framing participation as a quick demographic survey or market research exercise.

The pitch escalates once personal details are requested. One contributor noted the caller asked their age specifically, then immediately hung up after receiving the answer. Another report mentions the caller "dangling cash prizes" as motivation to complete the survey before abruptly disconnecting. A separate contribution describes the caller mentioning a drawing or competition entry tied to answering survey questions, presenting the interaction as a chance to "win" rather than straightforward research participation.

One report also mentions a caller asking about bulk billing removal for GPs and then pivoting to request donations to specific political parties, suggesting this number may cycle through multiple deceptive scripts rather than following a single scam pattern.

Call Patterns and Contributor Experiences

Contributors report calls from 03 8804 5818 across multiple years, with the earliest report dating to mid-2024 and the most recent to April 2026. The majority of calls go unanswered and leave no voicemail, though several contributors who did answer report the caller disconnecting within seconds of them speaking or providing requested information.

The non-operational callback pattern is reported by at least five separate contributors. Each describes attempting to verify or report the number by calling back within minutes to hours of the initial call, only to receive an automated message stating the number is no longer in service or is not operational. This pattern suggests intentional use of temporary or disposable numbers rather than a stable business operation.

One contributor described the experience as "extreme fraudulent calls, dangerous and opportunistic," while another noted the caller was an "AI person" rather than a human operator. The Optus network allocation to Victoria aligns with the Melbourne location reference in one early report.

What to Do If You Receive a Call from 03 8804 5818

If 03 8804 5818 calls you:

• Do not: Answer questions about your age, household income, or other personal details; provide banking or payment information; return the call if you're suspicious; engage with prize or competition claims
• Do: Let unknown calls go to voicemail; hang up immediately if the caller claims to be from a research organisation but sounds robotic or automated; block the number if it calls repeatedly; note the time and date for reporting purposes
• Verify independently: If genuinely curious about a research survey, contact the purported organisation directly using contact details from their official website (not information provided by the caller)

Call Timing and Channel Breakdown

Of the 15 reports for 0388045818, eight involve missed calls with no voicemail left, four involve calls the contributor answered, and three are categorised as other interactions (mostly callback attempts resulting in non-operational messages). The answered calls consistently show patterns of caller disconnection or hang-up, typically within seconds of the contributor responding or providing demographic information.

Reports span from July 2024 through April 2026, with no clear clustering to specific months or times of day. The absence of voicemails across the majority of unanswered calls is notable and differs from typical telemarketing patterns, where scripts are often left as voicemail to increase callback rates.
