One person in WA is among five people arrested in a major Australian Federal Police operation against people smuggling.
AFP Assistant Commissioner Steve Lancaster revealed the national raid at a press conference today, saying it was Australia's largest ever people smuggling strike.
Mr Lancaster says four of the five people - three Afghans, one Iranian and one Pakistani - came to Australia on boats.
He claimed they belonged to syndicates that were collectively responsible for 132 boats reaching Australia.
The man arrested in WA was already being held at the Immigration Detention Centre at Perth Airport.
It is understood the man is being interviewed.
He is likely to face five counts of people smuggling.
He is expected to face Perth Magistrate’s Court today.
Mr Lancaster said about 20 people-smuggling investigations were ongoing.
"Those who have not been picked up in the first scoop today, that does not mean you should sleep well tonight," he said.
