Southbank Montessori was founded in 2004 by Rachel and Simon Walker. Their interest in the Montessori Method of education began when they chose to send their own daughter to a Montessori long day care centre and continued as she attended a Montessori primary school. In August 2004, Rachel and Simon purchased a day care center in East Victoria Park. In the years that followed they worked hard to adopt and apply the Montessori Method.
After a few years it became clear that a larger centre would be needed, and in 2008 Southbank Montessori moved to its current location on Berwick Street. The centre was purpose built to meet the needs of a Montessori classroom. Southbank Montessori expanded again in 2010 with the purchase of a centre on Basinghall Street. This centre now houses the 2-3 classes.
