The man was diagnosed with acute Zika virus after arriving at the Royal Darwin Hospital with fever and a rash seven days after the bite. He'd also been bitten by mosquitos while holidaying in Bali.
Infectious disease experts are warning the fast-spreading Zika virus could be under-diagnosed in South-east Asia.
Their warning, carried by Fairfax newspapers in Australia, follows several reports, including that of a 27-year-old Australian who was infected after a monkey bite in Bali.
The man was diagnosed with acute Zika virus after arriving at the Royal Darwin Hospital with fever and a rash seven days after the bite. He'd also been bitten by mosquitos while holidaying in Bali.
The authors of the report, including doctors from the hospital and academics from the Victorian Diseases Reference Laboratory and the Menzies School of Health Research, wrote that while mosquito-borne transmission was possible, the monkey was a plausible route of transmission.
The disease linked to the Zika virus in Latin America poses a global public health emergency requiring a united response, says the World Health Organisation.
Experts are worried that the virus is spreading quickly, with devastating consequences. The infection has been linked to cases of microcephaly, in which babies are born with underdeveloped brains.
The WHO alert puts Zika in the same category of concern as Ebola.
