Pi Melbourne was established in 2005 we are based at 585 Little Collins Street Melbourne. Since 2006 we have established a vast array of clients that spread worldwide, we like to treat our clients on an individual basis as each job is tailor made to their needs. No two jobs are a like and that s why our staff are trained to listen and treat every job differently. There are many private investigators in Melbourne and we all have our different techniques but one technique that will never change is to always do what your client wants and at the same time to always give your professional opinion. Many of our jobs are varied, some are for cheating partners, corporate investigations, teenage monitoring and family law, they all have one thing in common, they all need surveillance. The cost of a private investigator varies as every job is different.
