World number one tennis player Novak Djokovic's entry to Australia has been delayed over an issue with his visa.
The player arrived in Melbourne on Wednesday, where authorities noticed that his team had made a mistake on his application.
Djokovic is due to play in the Australian Open, after being exempted from vaccination rules.
But his team had not requested a visa that permits medial exemptions for being unvaccinated.
All players and staff at the tournament must be vaccinated or have an exemption granted by an expert independent panel.
Djokovic has landed in Melbourne's Tullamarine Airport, and is awaiting a decision.
