Workplace Investigations
Sibley Lawyers: Your Trusted Partner in Workplace Investigations
Sibley Lawyers has a proud history of conducting external workplace investigations. In Australia, workplace investigations are structured processes designed to address allegations of misconduct or policy violations, ensuring accountability and a safe work environment while upholding employee rights.

The Importance of External Workplace Investigators
While HR or management staff may handle less complicated investigations, complex or sensitive allegations necessitate an independent external workplace investigator. This is especially true for cases involving senior managers or executives, or where there is potential for follow-on litigation as in Crowley v Modcon Group Pty Ltd [2024] FWC 1423. Poor internal workplace investigation saw Mr Crowley receive the full 26 weeks compensation cap for unfair dismissal under the Fair Work Act 2009 (Cth). An external investigator ensures impartiality and procedural fairness, reducing the risk of decisions being overturned on appeal.

Nurture In Harmony
I highly recommend Sibley Lawyers for anyone dealing with workplace issues, including personal injuries. After my union lawyers refused to support me in a workplace dispute, Justin Sibley and Jack McDonald stepped in and made all the difference. They were incredibly knowledgeable, responsive, and truly committed to my case. Despite the lack of support from my union, to which I had paid fees for 13 years, Justin and Jack worked tirelessly to ensure I was treated fairly and helped me achieve a positive outcome. Their expertise in employment law and genuine dedication gave me the confidence to move forward. If you’re looking for lawyers who will fight for you when others won’t, Sibley Lawyers is the firm to trust!

I have needed the services of Sibley Lawyers for a couple of years now. They are extremely thorough, knowledgeable and above all approachable and trustworthy. They have been dealing with my protracted issue that has been handled very professionally and successfully at every turn. When this is all concluded I hope to never need their services again but if I, or anyone I know does, Sibley will be the first call. Thanks team.

Justin Sibley and his team are the consummate professionals in law.
I have used his services as a retained client as a Qld Government employee, as well as being a personal client. Justin always impresses me. When push comes to shove, you need someone like Justin in your corner. Not only does he understand the law and all of its complex mechanics, but he has the ability to win with his attention to detail, unwaivering knowledge and courtroom charisma. As mentioned I Highly Recommend Sibley Lawyers to anyone needing legal representation, they’re a tremendous firm.


Luke Doherty
Sibley law and especially Nick Ware are amazing and I could not recommend a better criminal defence lawyer.
He’s professional, personable and very thorough. Always put my worries and mind at ease with his professional advice and very contactable, not fobbed off to a secretary.
The outcome of what I wanted, happened and I was also upfront and honest from the start with no judgement whatsoever from Nick.
I went into the experience alone and can really say I have come out with a great result and someone I’ll call a mate.
