Detectives raided Messina's Wattle Grove home and seized multiple electronic devices yesterday.
His charges do not relate to students at the school.
A letter told parents Messina's employment had been terminated immediately.
The letter said he had met "all government and school child safe checks".
Messina is in police custody and has been charged with intent to procure a person believed to be under 13 years for sexual activity, possessing child exploitation material and distributing it.
Counselling is being offered to the school community.
