Djokovic thanks supporters

World number one Novak Djokovic on Friday thanked people around the world for their support amid a visa row over Covid-19 vaccines that has seen him being detained at a Melbourne hotel ahead of this month's Australian Open.

"Thank you to people around the world for your continuous support. I can feel it and it is greatly appreciated," the Serbian wrote on Instagram.

Djokovic was granted a medical exemption from Australia's strict Covid-19 vaccination requirement following a review by two independent panels prior to boarding his flight, but was denied entry upon landing in Melbourne late on Wednesday.

The 34-year-old is currently housed in a government detention hotel in the suburb of Carlton.
