Nauru rejects Amnesty International visit

Nauru has denied Amnesty International access to the Australian-run immigration detention centre, the human rights group claims.

It comes after a team of United Nations human rights observers was denied entry to the camp earlier this month.

Amnesty International spokesman Rupert Abbott says the Nauru government has refused the group's visit request because it was an "incredibly busy time", despite the organisation offering alternative dates.

Since July, no asylum seekers sent to the island have received a refugee status decision.

"They continue to live in legal limbo, which adds to the already enormous psychological strain of being an asylum seeker," Mr Abbott said.

"Nauru should allow independent oversight of the detention centre."

There are 1177 asylum seekers detained on the island.

In February, the Nauru government increased visa costs for journalists visiting Nauru from $200 to $8000.

Comment has been sought from the Nauru government.
