Certified tools and documented methodology

We use Oxygen Forensic Detective — the same platform used by law enforcement agencies internationally. Every extraction is write-blocked, hash-verified, and fully documented to the standard required by Australian courts.

Our analyst provides independent expert testimony in criminal proceedings, coronial inquiries, and commission hearings — with rebuttal capability against opposing expert evidence.

Practical Guidance

Before You Engage Us

A few things to have ready before contact ensures we can commence quickly and maintain full chain-of-custody continuity from the outset.

01

Confirm lawful authority

We require evidence of lawful authority — warrant, court order, or appropriate statutory power — before commencing any examination. Have this documentation ready before making contact.

02

Prepare existing exhibit records

We integrate with and extend your existing chain of custody documentation. Bring your exhibit records to the initial engagement so continuity is maintained from the point of seizure.

03

Define the scope of examination

Targeted examinations are faster and produce cleaner reports. A defined scope — specific date ranges, applications, or data types — helps us produce exactly what the matter requires.

04

Advise us of hearing dates upfront

We structure our availability and report delivery around your court timelines. Early notice of hearing dates means we can guarantee delivery with time for legal review.

Common Questions

Agency FAQ

01 What tools do you use for extractions?
We use Oxygen Forensic Detective for mobile device extractions — the same platform used by law enforcement agencies internationally. Computer forensics is conducted using industry-standard imaging and analysis tools with full hash verification at every stage.
02 How is your chain of custody documentation structured?
Our chain of custody records include exhibit receipt documentation, storage conditions, hash values at intake and post-examination, and a complete handling log — structured to the requirements of the relevant court rules and compatible with existing exhibit records.
03 Are you available to give evidence at short notice?
We maintain scheduling flexibility for urgent matters. Contact us directly to discuss your timeline — we can often accommodate short-notice requests for hearing dates and interlocutory matters.
04 Can you handle encrypted or passcode-locked devices?
We can perform logical and advanced logical extractions on many locked devices, and full physical extractions on supported models. We'll assess specific capability against the device make, model, and OS version before commencing — and we'll be honest about limitations upfront.
05 Can you provide a rebuttal of opposing expert evidence?
Yes. We regularly review and rebut opposing expert reports in criminal proceedings — identifying methodological errors, unsupported conclusions, improper tool usage, or chain of custody deficiencies. We can provide a rebuttal report or a brief for cross-examination of the opposing analyst.
06 Do you operate under a non-disclosure agreement?
Yes. We can operate under an NDA or confidentiality deed where required by the agency or by the nature of the matter. Please advise at the time of engagement and we'll have the appropriate documentation executed before commencing work.

Client Feedback

What Clients Say

Real outcomes from real people — names abbreviated to protect privacy.

“We engaged DFG for peer review of a mobile extraction in a criminal matter where the defence had challenged the prosecution methodology. The independent analysis confirmed our approach was sound and provided the court with a second expert opinion.”

“Our internal digital forensics team was at capacity during a multi-agency investigation. DFG provided additional extraction capacity within 48 hours using Oxygen Detective — fully documented and chain-of-custody compliant from the outset.”

DF

“The expert witness report was one of the most clearly structured pieces of forensic evidence we've presented. The analyst's oral testimony was concise, authoritative, and survived cross-examination without issue.”
