Novak Djokovic's father decided against attending the Australian Open final on Sunday, following his controversial interaction with Vladimir Putin supporters on Wednesday.

Srdjan Djokovic was filmed with a man wearing a 'Z' T-shirt [denoting support for Russian armed forces] and standing behind a flag sporting the face of Russian president Vladimir Putin. 

Russian flags, the Russian Eagle banner, Belarusian flags, and items of clothing with the Z symbol are prohibited at Melbourne Park amid Russia's ongoing invasion of Ukraine. 

While he maintained that he was merely wishing to thank his sons' fans for their support, the footage sparked uproar.

As a result, Djokovic Snr did not attend his son's semi-final win over world No. 28 Tommy Paul on Friday.

The Ukrainian Ambassador to Australia, Vasyl Myroshnychenko, called for tournament organisers to prevent Djokovic Snr from watching his son take on Stefanos Tsitsipas at Rod Laver Arena on Sunday.

But just hours before the start of the final, Tennis Australia boss Craig Tiley revealed that Djokovic's father was free to take his place at Rod Laver Arena after accepting the Serb had inadvertently been swept up in the flags drama.

'It's his decision. We're going to let it be his decision and ultimately he's got to make the call,' Tiley said on Sunday.

'He didn't breach any event policy. That's really important because what's been written about what he [allegedly] said hasn't been correct and I think people are back-tracking from that. That's unfortunate that massive assumptions were made.'

However, Djokovic's father was conspicuously absent at the Rod Laver Arena, with the seat next to his wife Dijana left empty.

Ahead of the semi-final on Friday, Djokovic Snr said he'd opted to stay away to avoid becoming a distraction. 

'I am here to support my son only,' he said in a statement.

'I had no intention of causing such headlines or disruption. I was outside with Novak's fans as I have done after all my son's matches to celebrate his wins and take pictures with them. 

'I had no intention of being caught up with this.'

Tiley said he believed that Djokovic's father didn't realise he was posing with people carrying Russian flags.

'I know him personally and his family was devastated by what happened. It was not intentional and I agree with him and it was not designed to cause harm to anyone,' Tiley said.

'It was an unfortunate situation and the Serbian fans have been great. Every day they've been very active and noisy and boisterous and that adds to the whole colour of the event.
