Paul McGrath worked directly with Sydney Water's field workforce management in the development and implementation of a culture change program from late 2003 until 2006. Sydney Water's Annual Report for 2006 states:

The major field workforce business, Civil Maintenance, achieved an LTIFR of 18.4 at the end of June 2006 with 20 lost time injuries for the year against an LTIFR of 43.2 and 50 lost time injuries for the previous 12 months.

This significant improvement reflects the impact of the safety leadership program Be Safe Mate 2. The training, conducted over the past two years, focused on responsibility and accountability.
