A senior Chinese official's visit to Parliament House has prompted a security warning to staff working in the building.
Politicians and staffers received an email telling them to consider closing their doors and blinds while the chairman of China's Standing Committee of the National People's Congress was in the building.
"Suites and offices adjacent to the delegation movements may wish to ensure doors and blinds are closed during the visit for privacy," the message read.
The email, sent by the Department of Parliamentary Services and obtained by AAP, also warned of intermittent disruptions to wi-fi access.
"Within the identified areas, internet-connected devices including phones, tablets and laptops should be powered down.
"Where devices must be used, please ensure phones and iPads are updated with the latest software version and placed in lockdown mode, and laptops should have Wi-Fi and Bluetooth switched off," it said.
Zhao Leji flew into Canberra on Monday to meet Governor General Sam Mostyn and parliament's presiding officers.
He is not expected to make any public remarks during his visit to the nation's capital, and his conversations with Australian leaders have been shrouded in secrecy.
At the weekend, Chairman Zhao visited Brisbane's Lone Pine Koala Sanctuary and the gas and electricity company Arrow Energy.
On Tuesday, he will visit the National Gallery of Australia before flying out of Canberra's Air Force base.
