Corporate Client Testimonial - Sensis

Over the past 3 years, Two One Investigations has assisted Sensis with a number of workplace investigations.  At Sensis we have found their customer service focus refreshing and their professionalism beyond reproach.  They are easy to deal with and their team has an ability to put interviewees at ease, whilst at the same time incisively cutting through to the heart of a matter.


The expediency and autonomy of Two One Investigations’ work allows the Sensis’ staff to get on with their job, whilst the team’s attention to detail and thoroughness minimises the need for additional or supplementary statements when matters are listed for legal proceedings.


Furthermore, their impartial and objective manner ensures that interviewees respond to the necessary questions and that their statements are coupled with evidendentiary documentation.


As a National Injury Manager I have come across my fair share of investigators, and I consider Two One Investigations to be without a doubt one of the best operators in this niche field.

Private Surveillance Matter Testimonial

" I did not feel comfortable at first about hiring a Private Investigator but needed to in order to win my case in Court. From the first phone with call with Two One Investigations I knew I was in good hands. Alan and his staff performed their work in a very professional manner making sure they got the evidence you needed.
Thank-you Alan for all your help and being very compassionate to my situation"
