Home Affairs Minister Peter Dutton will hold high-level meetings in Sri Lanka, with people smuggling at the top of the agenda.
Mr Dutton is due to meet Sri Lanka's President Maithripala Sirisena, Prime Minister Ranil Wickremesinghe and his ministerial counterpart in Colombo on Tuesday.
The minister hoped his visit would send a message to Sri Lankans contemplating making the journey to Australia by boat.
