1956
Father Jim O’Byrne osa was appointed as the second parish priest of St Kieran’s.
In July two blocks of ground, adjoining the school grounds, were purchased with a view to building a proper church.
St Augustine’s College opened, initially in the Church Hall, moving into the school building later in the year.
1958
A new church hall was opened in Warringah Road, Forestville, to serve the needs of the parishioners in that area.
1959
The church at Forestville, named in honour of ‘Our Lady of Good Counsel’ was separated from the parish of Manly Vale and constituted as a parish in its own right.
Manly Vale continued to grow and with 276 children starting school at the beginning of the school year, further extensions to the school were ungently needed. Fund raising activities were increased, including the commissioning of the Wells organisation to spearhead the efforts, and sufficient money was raised to build a second floor on the school building.
Father O’Byrne & his assistant, Father Dennis O’Shea osa, organised the ‘Wells System’ to conduct a most successful ‘planned giving’ drive to raise money for the building of the new church.
1960
A cottage next door to the allotments was also acquired. This was used as a meeting place for parish activities for some years and consequently reduced the pressure on the use of the school buildings for parish purposes.
1961
Father Kieran O’Shea was appointed as parish priest
Father O’Shea proved very successful at raising funds — increasing the annual subscription pledged — and was looking forward to the time when he could build a church for the parish.
1962 & 1964
The parish rejoiced in the ordination of three young parishioners: John McCall & Abel van der Veer to the Augustinian Order and John Truman to the diocesan clergy.
1964
The priory was enlarged by a four rooms addition.
1968
On 9 June His Eminence Cardinal Sir Norman Thomas Gilroy blessed and officially opened the new church of St Kieran at Manly Vale. The church cost $140,000.

1974
Father O’Shea was able to announce that St Kieran’s was free of debt.
The parish now needed a meeting place to accommodate meetings of numerous groups in the parish & Father O’Shea purchased a cottage, for this purpose, at 73 Gordon Street.
1975
Father Patrick Crilly osa was appointed parish priest. He purchased a house and property in King Street to provide for the continuing needs of the school, purchased a new electronic organ for the church and initiated a new ‘planned give scheme’. He built a new priory, allowing the old living quarters to be changed into school offices.
1983
Father Gerry Dullard replaced Father Crilly as parish priest. He continued the expansion of parish activities.
