An Australian United Nations worker has been found dead in Fiji before her husband was seriously injured falling from their balcony.

Jennifer Downes was found dead at her Fiji home just after 1pm on Tuesday in the capital Suva, just weeks after she and her husband had moved there with their three children.

Police have confirmed that the death is being treated as a suspected murder.

Ms Downes’ husband Henry Lusaka John was found with serious injuries at the home after it was believed he fell from the balcony.

Suva police say Mrs Downes had no visible marks on her body.

Ms Downes was working for the UN World Food Program in the Pacific, and Mr John, an Australian citizen originally from Congo, also worked for an international organisation.

He was taken to Suva’s Colonial War Memorial Hospital for treatment.

An Australian Department of Foreign Affairs and Trade spokesman told AAP consular assistance was being provided to the family of the Australian woman.

“Owing to our privacy obligations we will not provide further comment,” he said.
