It is hoped to install a ring of eight bells during 2007 to commemorate the 150th anniversary of the church building.

Holy Trinity church like many other church buildings in Australia was designed to hold a ring of bells but they have yet to be installed.

The Trust has been actively looking to locate and acquire bells for this project and so far five of the eight bells have been located.

The pre-2003 ring of bells was cast by four different founders spanning 2 centuries. The bells are to be replaced by a modern ring of twelve and several of the old ring are to be re-used elsewhere. The old 7th bell is destined to become the tenor at Holy Trinity. It was cast by Abel Rudhall in 1754.

The Keltek Trust acquired a large quantity of former buoy bells during 2002 and these have proved very useful for a number of projects. ANZAB purchased two bells from the Trust and one of these is expected to become the 4^th of the ring of six.

Several  other redundant and surplus bells have been acquired for the project. They include bells from redundant churches in Scarborough and Croydon.
