The Archbishop of Canberra and Goulburn has put parishioners on notice that some Masses will be cancelled unless more people attend, reports The Canberra Times.
Archbishop Mark Coleridge also believes Canberra has about twice the number of Catholic schools, parishes and churches that it needs.
Archbishop Coleridge will make a raft of recommendations before the July meeting of the Council of Priests.
Among them is a proposal to cancel Masses if they are not attended by at least 15 adults.
In his address to last November's archdiocesan assembly, now made public, Archbishop Coleridge said, ''And then there is the great question of Canberra ... I sometimes think - this is a bit wicked - that we have about twice the number of schools and parishes and churches in Canberra than we need.''
The questions referred to include a shortage of priests and declining attendance.
The final report of November's assembly says there was wide recognition of the special needs of rural parishes and the relative oversupply of priests in Canberra.
