St Thomas' Primary School, Sale will move into a state-of-the art primary school facility on the site and will be re-named Our Lady of Sion Catholic Primary School to honour the rich history of the Sisters of Sion. A strong link to St Thomas' will be maintained with a $12.5 million purpose-built. Learning Neighbourhood to be known as the St Thomas' Centre. The new building has been made possible with the support of a $3.6 million Capital Grant from the Australian Government.


The first two floors of the Sion convent building will be repurposed for contemporary primary education use for Years 4 to 6 and will include connected classrooms, along with STEM, Library, Art, multimedia, administration, and office spaces. The beautiful convent chapel will be an inspirational and prayerful space for students.


The Ratisbonne Leadership Centre will occupy the top floor of the convent building which will be refurbished and re-purposed as a specialised facility to deliver teacher and school leader professional learning programs to support Catholic schools across the Diocese of Sale. With independent access and carparking, it will support DOSCEL’s efforts to promote expert teacher practice and deliver teaching and learning excellence.


This exciting project is being led by Monto Project Managers, with Y2 Architecture as the lead Architects. Melbcon Builders are on-site, laying the groundwork for construction to begin, with a planned completion in early 2027.

“This new building is more than just bricks and mortar; it is a commitment to nurturing minds and shaping futures. This state-of-the-art building project represents a vision for the future. It will provide modern, safe, and inspiring spaces for staff and students to grow and thrive.”


Catholic Bishop of Sale, Most Reverend Greg Bennet:


“The preservation and revitalisation of this much-loved Sale landmark not only protects our heritage, but as custodians of the site we have been given the opportunity to create a beautiful new place of learning for our young people that will enable them to grow in their love of Jesus in an enriching environment. This learning environment is deeply connected to our mission to proclaim the good news

of Jesus Christ.”


Director of Catholic Education for the Diocese of Sale, Mr Paul Velton:


“St Thomas' Primary School was established by the Sisters of Our Lady of Sion more than 50 years ago so this in many ways is a return to its spiritual roots. It is also a wonderful opportunity to honour the past and invest in this new state-of-the-art school building for our students and ensure Catholic education continues to thrive on this site for another 125 years.”

Australians reported 481,523 scams in 2025 , with 274,577 reports involving financial losses totalling $2.18 billion . Behind those numbers are scams that are becoming increasingly difficult to spot. For organisations, one of the most convincing can begin with something as routine as an invoice. Invoice fraud is becoming increasingly sophisticated. The email may come from a supplier you know. The invoice may look exactly like previous ones. The amount is correct, the project is familiar, and the message may even sit inside a genuine email thread. The only thing that's changed is the bank account. That one change can redirect thousands of dollars into a cyber criminal's hands. How it happens Invoice fraud, also known as payment redirection fraud, is a common form of Business Email Compromise (BEC). Criminals gain access to a real email account - through phishing, stolen credentials, malware or a data breach - then quietly monitor it. They learn who approves payments, how invoicing cycles work, and wait for the right moment to intercept a genuine transaction and simply change the bank details. Because nothing else changes, it's very hard to spot. Example of What a Scam Looks Like

In 1956, a priest with a vision and a community with faith came together to solve a problem. Catholic schools across Melbourne were overflowing. Families were growing. Government funding for Catholic education was simply unavailable. And so Fr James Wall, later honoured with the title 'Father of the Funds', established what he called the Schools Provident Fund (SPF): a new way for the Catholic community to pool its resources, invest in its future, and care for one another. The very first school funded through that vision was Sacred Heart Parish Primary School in Preston, Victoria, which opened in 1957 and became an instant success, laying the framework for what would follow. The movement spread across Australia and New Zealand, growing from a solution for Catholic schools into a broader vehicle for funding parishes, hospitals, aged care and social services. Seventy years later, that vision is very much alive.

For the parishioners of Our Lady of Lourdes in Bayswater , the newly renovated Parish Hall is far more than a building. It is the fulfilment of a long-held dream; a place where a vibrant and growing Catholic community can finally come together, share life, and welcome others. Supported by a $1.85 million loan from CDF, the renovation has transformed what was once an ageing and inadequate space into a modern, welcoming hall that will serve the parish and wider Bayswater community for generations to come. A community that needed a home Our Lady of Lourdes Parish has been a cornerstone of Catholic life in Bayswater for more than 60 years, celebrating daily Mass throughout the week and welcoming between 450 and 600 parishioners and visitors across four weekend Masses. It is a community rich in faith, culture and connection, and one that had long outgrown its ability to gather together in a shared space. For Parish Priest Fr Sabu, taking on the renovation project was both a personal commitment and a responsibility to those who had built the parish before him.
