Abusive Language

I have just been called a f***ing fa***t by a tenant as he was driving passed on common property. He had his children in the car with him at the time and when I asked him to repeat it he said get witnesses next time. I have already been screamed at in the street and called a P**h Pusher, once again in front of the children. Can I complain to the Strata manager about the language used on the property? I understand I will have to go to the police about the street incidence. The family are renters and have been there twelve months and don’t look like moving.
