A Dover Heights man will face court on Thursday after allegedly making threatening or sexually explicit calls to about 100 people across Queensland, NSW and Victoria since 2018.
Gerard Vamadevan, 53, has been charged with almost 30 telecommunications offences after allegedly making the calls.
The calls were made to men and women known to Vamadevan in both his personal and work life, police say. Police claim 29 people received multiple calls.
The calls were linked to more than a dozen mobile numbers.
Vamadevan was arrested following a vehicle stop about 7.30am on Wednesday, when police seized two mobile phones.
Police later executed a search warrant at a nearby home, where they seized a further eight mobile phones.
Vamadevan was charged with 25 counts of using a carriage service to menace/harass/offend, and two counts each of using a carriage service to threaten to kill and using a carriage service to threaten serious harm.
He was refused police bail and will appear at Waverley Local Court on Thursday. Police say further charges are expected.
