Excellent news: our strata received several letters from {a major network – name withheld by editor} threatening to instal equipment and telling us we could not stop them. We responded by asking our Strata Managers to let them know that they did not have permission to enter the premises and any attempt to do so would be trespass and the police would be called, that we were referring their letters to the Ombudsman, and also seeking legal advice. So far so good, but this will also help.
