Novak Djokovic said "human error" was behind a mistake made on his Australian entry documents that breached the country's strict laws on reporting recent travel, as the government weighed whether to deport the player.

Djokovic was held in immigration detention in Melbourne for several days after his visa was canceled by border force officials, who questioned his medical exemption for a requirement to be vaccinated for COVID-19.

He was released on Monday when a judge quashed that decision, saying the cancellation of the visa was "unreasonable" because the player was not been given time to consult with lawyers and tennis officials when he arrived in the country.
