History
OLMC was first established in the 1930s on the Esplanade at Cronulla and was located there until 1960.
The current property at Burraneer was purchased from Mr Charles Duncan who lived there for a number of years before leasing it to the Cronulla Country Club.

1960-1965
The College
was officially opened and blessed on Sunday October 16, 1960 by His
Eminence N.T. Gilroy, Archbishop of Sydney. The total number of students
enrolled was 199 with 7 staff and Sister M. Alphonsus the Principal.

1965-1970
In 1966 the Catholic Education Office established Our Lady of Mercy College
as a Regional School and enrolments increased to 439. Temporary buildings
were erected in 1967 on the bowling greens and the Science Block was completed.
Principals during this period included Sr. M. Anne Ryan, Sr. M. Paulinus
and Sr. Immaculata Hegarty.

1970-1979
The old Art cottage was purchased in 1974 and the Library and classroom
extensions were officially opened by Cardinal Freeman and the Hon. E. G.
Whitlam, then Prime Minister. In 1976 the old Music room was built. Principals
of this decade included Sr. Pauline N. Smith and Sr. Margaret Doyle.

1980-1989
In 1982 the Sisters of Mercy Community moved out of the the Convent and
in 1984 allowed the school to extend into this part of the building. Renovations
and refurbishments including verandahs and staircases to link the buildings
were completed in 1988.
Building projects continued in this decade which saw adjacent land purchased
to house a new Art demountable, linking of the two existing buildings, resurfacing
of the basketball court, extensions and development of a Home Science (TAS)
area. The new extensions were blessed and opened by Bishop David Cremin.
In 1989, after extensive community consultation, a new uniform was introduced
replacing the traditional yellow and brown. With the uniform change came
the new school colours of red, white and blue.

1990-2005
The Art rooms moved back across to the main site and demountables across
the road were removed. Extensive building work was completed in late 2003
and the College now has a multi-purpose hall, new music and practice rooms,
and 5 new general classrooms.
