Deputy Prime Minister Barnaby Joyce has tested positive for COVID-19 in the United States, it has been announced.
The Nationals leader is currently in Washington DC and chose to get tested after suffering from mild symptoms.
Mr Joyce is currently on a 10-day overseas trip which has included a stop in London where he met with UK ministers, discussing the AUKUS pact.
Speaking to ABC New England North West, Mr Joyce said he was "frustrated" at the prospect of being locked in his room for 10 days.
He added: "We arrived here from England, I chose to get a test and I tested positive and all my colleagues tested negative.
"That's the luck of the draw I suppose."
In a meeting with Deputy Prime Minister Dominic Raab, the pair "[reaffirmed] our great nations’ enduring partnership", the British MP said.
In Washington, Mr Joyce is reported to have set up meetings with Republicans and Democrats to discuss the influence of Facebook and other social media giants.
Speaking to The Australian Financial Review newspaper ahead of the visit, Mr Joyce said he wanted to work with congressional leaders to curb the power of Mark Zuckerberg, adding the Facebook founder was "not above democracy".
“Mr Joyce will remain in isolation until further advice,” a statement from the Deputy Prime Minister's Office said on Thursday.
"Remaining members of the delegation have tested negative."
Deputy Nationals leader David Littleproud tweeted on Thursday: "I’ve been in touch with Barnaby this morning, he let me know he tested positive for COVID-19.
"He's isolating in the US until it's safe for him to come home and we wish him all the best for his recovery."
In March 2020, Mr Joyce's cabinet colleague Peter Dutton was the first federal MP to be diagnosed with coronavirus.
The current Defence Minister was briefly hospitalised after waking up with a temperature and a sore throat.
Mr Dutton said he had no idea how or where he picked up the virus but believes it was in the US where he had been attending meetings.
"But I was pretty, you know, pretty militant about the hand sanitiser," he added.
