McMahon takes special interest in all areas of pastoral work.

There have also been various programmes in the diocese, such as the Diocesan Renewal Programme, the Movement for a Better World (1982); the Ministry to Priests Programme (1984); and a ten-year pastoral plan for the diocese leading up to the year 2000.
He was responsible for the building of the diocesan offices 'Cathedral House' in Brentwood (1982), followed by the building of a new Cathedral in 1989 by the classical architect,
Quinlan Terry. It is the first cathedral to be built in the classical style since St. Paul's. McMahon has also founded a Cathedral and Choral Trust and extended the Choir School (2000).

As of December 2018, there are nine students in training for the priesthood.
