The number of suspended school students in the Keira electorate has surged 25 per cent in just three years.
According to Department of Education figures, in 2016, 666 students in the electorate were suspended for a range of reasons.
That number climbed to 705 the following year and to a whopping 826 students in 2018 - a 25 per cent jump in just a handful of years.
With two terms still to go in 2019, it looks set to be another big year for suspensions; as of May 28, the number of suspensions sits at 390 students.
The data was released after the area's MP Ryan Park asked Education Minister Sarah Mitchell for details of school suspensions in his electorate.
"What we are seeing is a trend in the wrong direction," Mr Park said.

"More and more students are being suspended for poor behaviour and worryingly more students are being suspended for bullying at our local schools."
Mr Park also asked the minister how many of those suspensions related to the bullying of another student.
According to departmental figures, the rates of bullying of students was also increasing.
In 2016, 24 children were suspended for bullying a fellow student, rising to 31 in 2017 and 33 in 2018.
As of May 29, there have been 25 suspensions for bullying of students in the Keira electorate so far this year.
As a former teacher, Mr Park was particularly concerned about the issue of bullying.
"The government needs to take more action when it comes to bullying," Mr Park said.
"Students have the right to go to school without fear of being bullied in the playground. Bullying can have long-term detrimental impacts on young kids.
"I want to see this government providing more support to local principals and teachers who quite frankly should be focused on teaching rather than dealing with bullies."
A Department of Education spokeswoman said the body "was serious about safeguarding the well-being of our students and staff".
"More than 800,000 students are enrolled in NSW public schools and the majority of them engage successfully in their schooling every day," she said.
"While school enrolments have increased over time, the number of students suspended from school is very small and has remained stable over time."
There are two types of suspension - short (up to four school days) and long, which can cover up to 20 school days.
The majority of NSW school suspensions are short suspensions, according to Department of Education data.
