About Us

Over 40 years meeting and exceeding our client’s needs…

The O’Brien’s story started in the 1960’s as a division of F. G. O’Brien Industries (established in the 1930’s and later to become O’Brien glass). F. G. O’Brien was a major shop front and glazing company and the new division specialised in door service and locksmithing to grow with the changing needs of our clients.

This division was to become a separate company in 1971 – W. F. O’Brien Pty Ltd. Under its current management, W. F. O’Brien Pty Ltd continues to develop lock and door service expertise. We are a member of the master locksmiths association of Australia and are both D.E.W.E.R and S.C.E.C endorsed.
