Three asylum seekers on Nauru spent a night in the local police station following damage to processing facilities on the island.
A spokesman for Australia's Department of Immigration says there was a minor disturbance at the temporary regional processing centre at Topside, Nauru, on Sunday night.
The spokesman says there was minor damage to kitchens, tents and lights, but no staff or asylum seekers were injured.
Nauru police had also attended the unrest.
The spokesman told AAP that as a result of that, three clients were held overnight by the Nauru police.
The three men returned to the Nauru processing tent camp yesterday.
The spokesman says any charges would be a matter for the Nauru government.
Nauru has the capacity to hold 1500 asylum seekers once the facility is built.
