But Mr FitzSimons is "proud" to say that every day at Dapto High School, students and staff do their "utmost to resist, to push back, to support, to sort out the situation".
His comments come on the back of a new report showing Australia is among the worst OECD nations for school bullying.
The Organisation for Economic co-operation and Development report, released in Paris last night, found that 37 per cent of Australian principals deal with acts of intimidation or bullying among students at least weekly.
The average for industrialised countries is just 14 per cent - making Australian schools among the world's worst for bullying.
The global survey of 192,000 teachers in 48 industrialised nations shows that Australian teachers are struggling with rowdy and disruptive classrooms.
It shows that 60 per cent of teachers are "frequently calming'' disruptive students.
The OECD's Teaching and Learning International Survey (TALIS), which is released every five years, also shined the spotlight on the impact of technology on student safety.
More than 10 per cent of Australian principals claimed to be dealing with a report of a student being subjected to the posting of harmful information online at least weekly.
The issue was substantially more prevalent in Australian schools than in most other countries, with only England reporting a higher rate.
NSW Secondary Principals Council president Chris Presland said the findings echoed those of recent principal wellbeing surveys and seemed to mirror declining standards of civility in broader society.
Mr FitzSimons said Dapto High School tried to address the issue of bullying by normalising the process of seeking assistance.
"What we say to our kids is bullying is in our human DNA, it is in cricket clubs and Federal cabinet, it is everywhere," he said.
"What the research says is if you observe bullying and you do nothing about it, you are more likely to become involved.
"If you are bullied and nothing is done about it, you can become a bully. So everyone has got skin in the game here.
"We are active on every level. Initially we will give a student a warning. If the behaviour is repeated there are consequences and we always involve the parents."
Dapto High School also employs a boys mentor and girls supervisor as part of its wellbeing program.
Meantime, the TALIS report also found Australian public school teachers face higher workloads, fewer resources and more administration duties than global averages.
Over the last five years time spent on administration has increased, and is now 33 per cent higher than the OECD average, much to the displeasure of Australian Education Union president Corena Haythorpe.
"It is critically important that Departments of Education provide sufficient support to beginning teachers in these schools to enable them to do their job well and teach students despite the overwhelming pressure they are under," Ms Haythorpe said.
"As recommended by the OECD, this includes induction programs, reduced teaching load, access to regular mentoring and secure, ongoing employment.
"Escalating workloads impacts on teaching and learning in schools. Teachers should not be spending more time on administration than on teaching,"
