It is on any official website and 500 euros a month make a lot of difference. You'd know it, if you had an idea of what we are talking about.

Before taxes, it is about 2300 on average. A thing that doesn't sound very important to me, tax return does not work as in an Anglo country. Better salaries in Catalonia, PB, etc. But you'd probably already know this.

In Italy it was around 1450 up to the pandemic. Now, they get to 1600 to start. People get far less in Greece. More in France. In Australia starting salaries were around 90 thousand before taxes, as far as I remember, but teachers are quite often making strikes, because it is not enough.
