In the early 1990s the Rockingham Congregation of the Uniting Church started to think about possibility of establishing a low fee Uniting Church school in the southern suburbs along the lines of St Stephens in Duncraig.

The idea was endorsed by the Synod and the Uniting Church Education Commission, under the leadership of its Executive Officer, Revd Owen Roberts, started the enormous amount of work that was needed to purchase land, meet Government Regulations, build the school, appoint staff, set up an interim Council and enrol the first students.

Mr Doug Burtenshaw was the Foundation Principal and Mrs Lillian Hadley was the first Chair of Council.

The motto of the College became "Uniting in Faith and Service" and mid blue, rust and oatmeal, reminiscent of ocean, settler hardship and farming, were selected as the College colours.

Building began in July 1996 with stage one being completed on 29th January 1997, one day before classes started on 30th January. The school opened with 221 students, from Kindergarten to Year 8, and 24 staff and in September the Childcare Centre started to operate.

During first term 1997, the Tranby College Prayer was written by Tranby students and staff in preparation for the Official Opening on 18th May 1997.

Tranby College Prayer

Dear Heavenly Father,
We give you thanks for new beginnings
and for the opportunities which Tranby offers us.
We seek your guidance
as we learn to trust You for our hopes and dreams.
Help us to nurture new friendships,
to be ready to accept differences,
to recognise each other's gifts and talents,
and to work together for the common good.
As we pray, live and learn,
May Your love unite our families
And may our College be a visible witness
to Your love in our community.
In Jesus' name we pray.
