Tasmanian police are reminding international students about safety ahead of today's start of the university year.
It is almost four years since Chinese student Zhang Yu, known as Tina, was murdered.
It was a time when multiple racist attacks rocked the University of Tasmania.
The university, police and the Hobart City Council have joined forces to improve the safety of more than 5,000 international students.
Inspector Glen Woolley says increased CCTV cameras and better street lighting have helped over the past year.
"There's only been 20 international students who've been involved in some sort of incident around the Hobart area."
But he says students must remain vigilant.
"The main thing is to get them to use their intuition, having a gut feeling about knowing what's safe and what's not safe," he said.
"When they have a feeling about being not safe, do something about it straight away, to make sure they call friends, call police, or leave the area."
International students are being urged to walk in pairs and avoid walking alone in dark areas.
Graduate Jason Zu was assaulted in Hobart last year.
He says there is still work to be done, including improved bus services and an on-campus interpreter.
"I really hope we can see more support from the local community".
It is a critical issue for the university which is aiming to double its international intake.
Several international student societies took part in a forum in Hobart yesterday.
The Migrant Resource Centre's Archana Aril says there are many important issues to tackle.
"Often a lot of them feel isolated. They do hang out in cliques with their own communities," she said.
"Our intention is to get them to reduce their feeling of isolation and really participate in events and other activities. It's creating the bridge or links with other agencies, as well as the community."
