Four people who have gone missing have been considered potential victims after a bag of human bones was discovered at Kangaroo Point.

The human remains and clothing, some within a bag and some close by, were discovered by a male who was walking through long grass near Lower River Terrace about 10am on Monday.

Acting Detective Senior Sergeant Warren Gibbs said police were appealing for information from anyone who might have seen suspicious activity in the area over the past 12 months.

"As you may be aware, Lower River Terrace is a well-utilised area, it's right near the rotunda as you come down the stairs there," he said.
