I intend to set-up an auto dialler on a silent number, with a pre-recorded polite and informative message. I will anonymously and simultaneously notify multiple staff, on their advertised numbers, at the headquarters of the fitness club that runs the gym in our building. The notification will advise, in real time as its happening, of a noise disturbance to building residents, created by weight lifters dropping weights in their gym. The announcement will also ask to have the noise stopped now. Would this action be legal and not a breach of privacy in the state of Victoria? If not what part is illegal under commercial law? Thanks.
