Preparations for US President Barack Obama's visit to Australia are being ramped up, with dozens of NSW police officers being sent to the Northern Territory to bolster security.
Mr Obama is due to visit Canberra and Darwin on Thursday as part of a whistle-stop, much-delayed visit to Australia.
NSW Police on Monday confirmed it is sending 37 field and specialist officers to help with security in Darwin.
The officers will conduct routine patrols, traffic and public order duties.
"Our officers are experienced in providing support for other states, most recently we deployed a large number of officers to Western Australia to assist with CHOGM," Superintendent Craig Sheridan said in a statement.
"It is an honour to be able to support our counterparts with such a large event where the eyes of the world will be on our police officers."
The additional policing is part of a huge operation surrounding Mr Obama's visit, involving both US and Australian security forces.
Up to a dozen F/A-18 Hornets and other defence force aircraft are set to patrol Canberra and Darwin during the visit.
