Short answer: Triage Forensics provides professional mobile phone and digital device forensics across Australia for criminal defence, civil litigation, family law and workplace matters. The service covers secure data extraction, deleted message recovery where feasible, location timeline reconstruction, app analysis and court-ready reporting.
Mobile phones now sit at the centre of many legal disputes, from a text that allegedly shows intent in a criminal matter to GPS records in an employment dispute. This guide explains what mobile forensics involves, how findings become usable evidence, and when you should engage a specialist.
What does Triage Forensics do for phone investigations?
A typical phone investigation follows five defensible steps:
- Scope and triage: agreeing exactly which questions need answering so the work stays focused.
- Secure preservation: handling devices to avoid overwriting recoverable data, with a documented chain of custody.
- Extraction: using validated forensic tools on verifiable copies rather than casually opening originals.
- Analysis: reconstructing conversations, timelines and location history against your questions.
- Reporting: a plain-language report covering methodology, findings and honest limitations.
What data can be examined?
Depending on the device model, operating system and security settings, an examination may cover:
- Contacts, call logs and messaging (SMS/MMS and app messages such as WhatsApp or Signal).
- Deleted content where technically recoverable.
- Photos, videos and documents with timestamps and metadata.
- Browser history and search activity.
- App usage records across social media and productivity tools.
- Location data from GPS, Wi-Fi, Bluetooth and cell towers.
Location timeline reconstruction
One of our most requested services is reconstructing where a phone was over time. Sources include:
- GPS coordinates logged by maps, navigation and photo apps.
- Wi-Fi network connections, which reveal proximity to known networks.
- Bluetooth interactions with devices or beacons.
- Cell tower records showing which tower served the device and when.
- App records from fitness trackers, ride-share services and social check-ins.
Reading location evidence carefully
Location findings are powerful but not infallible:
- GPS accuracy varies sharply indoors.
- Cell tower data indicates an approximate area, not an exact address.
- A phone’s movement doesn’t always prove a person was present, because someone may leave their device behind.
- Wi-Fi and Bluetooth records show connections, which isn’t the same as the user being present.
A credible report states these limits rather than overstating conclusions, which is essential when evidence is cross-examined.
Deleted message recovery: what’s realistic
Recovery of deleted messages depends on:
- How long ago they were deleted.
- The device model and operating system (encryption has changed significantly, especially on modern iPhones).
- Whether backups or cloud sync captured the content before deletion.
- Subsequent device use that may have overwritten storage.
We tell you honestly what can be recovered rather than promising everything. That honesty is critical when a finding will support a legal decision.
Standards for Australian courts
For phone evidence to be relied upon in an Australian court, the forensic work needs:
- A documented chain of custody.
- Validated extraction tools, with their limitations disclosed.
- Findings that satisfy the court’s requirements for expert evidence: relevant, based on specialised knowledge (see Dasreef Pty Ltd v Hawchar), and transparent enough to be tested.
An independent expert also owes a duty to assist the court rather than advocate for a party, which strengthens credibility when findings are challenged by an opposing expert.
Who uses this service
- Criminal defence lawyers testing prosecution claims about messages or whereabouts.
- Civil litigators, including in insurance and defamation matters.
- Family lawyers, where communication records are relevant.
- Employers and HR teams investigating misconduct, IP theft or off-site conduct.

Frequently asked questions
What does Triage Forensics do for phone investigations?
Triage Forensics extracts, preserves and analyses data from iPhones and Androids using forensically sound methods. This covers contacts, calls, deleted messages where recoverable, photos and media metadata, app activity and location records, delivered in a clear report with a documented chain of custody that can be used in court.
Can Triage Forensics help reconstruct a phone’s location timeline?
Yes. Location timelines are reconstructed from GPS, Wi-Fi connections, Bluetooth interactions, cell tower records and app data to map where a device was over time, with the limits of that evidence clearly explained.
Are Triage Forensics reports accepted in Australian courts?
Reports are prepared to meet the standard Australian admissibility requirements for expert evidence: relevant, based on specialised knowledge, with documented methodology and a clear chain of custody. Whether any given report is admitted depends on the court applying those rules.
What data can be recovered from a phone?
Recoverable data varies by device and app. Contacts, call logs, messages (including deleted ones where technically possible), photos and documents with metadata, browser history and app usage records can typically be examined using validated forensic tools.
