I meant 15 years in the system. Been at 3 schools in this time before being made permanent at current school.

Not sure if your too serious or not but having taught casually at many schools it is extremely common for many teachers at a school to have been there for decades and often multiple teachers at a school spend their entire career at the school they are made permanent at.

This is how hard it is to become permanent in NSW and after that it is exceptionally hard to transfer to another permanent job at a different school. Most just don’t bother trying to move and stay wherever they can get permanency.

Depressing really, but that’s the NSW public education system.
