I didn't say they weren't dodgy. I hate demountables as a rule. This doesn't alter the fact that they remain as an important part of CHS history.   As for your objection to the word "permanent" you might also be aware that until recently, the entire school was scheduled to be levelled to make way for unit blocks, with all the students to be relocated to the Kuringai College site.This was  only avoided by the re-routing of the Epping-Chatswood railway.

Nothing is "permanent" by those standards. As For Fred's "contribution" I can only urge him to pay attention. I haven't proposed making any comparative entry, merely that the ESL buildings were used exclusively by Vietnamese refugees.
