Several days after arriving home to Sydney, two men in their 30s developed mild illnesses, with doctors determining symptoms "clinically compatible" with the virus.

"Urgent testing results for one of the men is consistent with monkeypox, making it the fourth case in NSW.
"His companion is likely to be confirmed as the fifth case," NSW Health confirmed in a statement.
Both men are isolating at home as the health department undertakes contact tracing.
Investigations to date have identified no high-risk contacts in NSW and these new cases are not connected to the three previously reported in the state.
