Hundreds of Victorian teachers are walking off the job today - demanding politicians in Canberra get kids off Nauru.
Recently Prime Minister Scott Morrison watered down a supposed plan to end their indefinite detention by Christmas, labelling it a "guideline".
Ahead of the rally, Teachers for Refugees spokeswoman Lucy Honan told AAP it was "time to close the camps".
"We are taking this action because we are so concerned about what has been happening on Manus (Island) and Nauru," she said.
Honan added it was up to teachers to set an example.
"A lot of us are teachers with kids who have come from refugees backgrounds. It is impacting the classroom. It is a live issue," she said.
"We have been given responsibility for the children."
Both public and private schools are involved in the strike action, which kicks off at 2:30pm at the State Library of Victoria.
Protests will also be taking place in other Aussie cities including Brisbane and Sydney.
