Djokovic fans, refugee supporters and anti-vaxxers protest in Melbourne

Both Novak Djokovic supporters and refugee advocates have taken to Melbourne streets to protest after the tennis star was placed in a Melbourne detention facility yesterday.

Djokovic fans have marched down Swanston Street in Melbourne CBD draped in Serbia's national colours and chanting, "Novak, we love you."

The world number one is being held at the Park Hotel in Carlton for four days as he awaits his day in court to appeal against the Australian Government's decision to cancel his visa.

The hotel is guarded by police and his room is beside where two dozen asylum seekers - some who have been imprisoned for nine years - are staying.

The asylum seeker's supporters also convened in Melbourne today, chanting, "Free the refugees".

Supporters of the anti vax and freedom movement also gathered in the city from midday.

Small groups of police officers monitored the groups of protesters.

Most of the protesters cleared out when heavy rain hit Melbourne early afternoon.
