The school has been planned for a student population of around 500 students.

The new school is located in the Sunbury Parish with the zoning boundary taken from south of Gap Road. Our enrolment policy and a map of the enrolment boundary can be found here.

Please complete this form and enrolment forms will sent immediately to you.

Holy Trinity Catholic Primary School will be open to all families who are supportive of the Catholic mission and traditions of the school. According to guidelines set by Catholic Education, priority entry will be given to baptised Catholic students.

As Catholic Schools are not fully funded by governments we have to charge fees.  It is always our aim to keep these as affordable as possible.

Below is a breakdown of what our fees are for 2024 as endorsed by our School Advisory Council will be:

  • Family Fee: $2,365 – This is a per family charge no matter how many children.
  • Individual Fee: $380 – Per child and covers everything the children need including incursions, excursions, sports and sacramental expenses

In 2024, Holy Trinity partnered with Edstart to streamline the fee payment experience and provide as much flexibility to families as possible. You will have a range of payment options available free of charge and there will be a dedicated local Customer Success Team available to assist with all your enquiries.
