United Australia Party chairman Clive Palmer is being tested for COVID-19 after being taken to a Queensland hospital with symptoms.
A spokesperson for Mr Palmer confirmed the 67-year-old had been taken to Pindara Private Hospital on the Gold Coast via ambulance.
He is expected to return home tonight.
Queensland Ambulance Service said three ambulances were called to a Paradise Point address at around 11:00am where a man was transported to hospital for a medical condition.
Mr Palmer was expected to address the National Press Club in Canberra on Tuesday but the event was cancelled after it was told he had COVID-like symptoms and had been given medical advice not to travel.
Speaking at anti-vaccination protests, the United Australia Party chairman has told crowds he is unvaccinated against COVID-19.
Since the onset of the pandemic, Mr Palmer has faced criticism for spreading misinformation about the risks of COVID-19 vaccine and for addressing anti-vaccination protests in Brisbane.
