And Gielnik is confident Australia's extended Olympic qualifiers campaign won't derail her from dealing with some unfinished business for the Matildas.

Tournament organisers were forced to delay Australia's start to the qualifying stage until Friday, due to China's team being isolated by the coronavirus.

It meant the Matildas won't face the Chinese until Wednesday week, one day after Gielnik was expected back with Bayern Munich.

Gielnik is yet to speak with her German team about the dramas but is hopeful of being given some leeway due to the extraordinary circumstances.

A number of other Matildas playing in Europe or recently signed to overseas clubs have also been affected.

"I've got a pretty good relationship with the club and I'm not missing any games, so I can't see as to why they wouldn't be OK," Gielnik told AAP.

"I really hope they can budge a little bit and give me those extra days to play that last game. I would understand if we were missing a league game or something.

"But I'm really hoping I've done a good enough service to that club that they can give me that leverage to stay here and play that last game."

And that's because the Tokyo Games hold plenty of significance for Gielnik.

The 27-year-old was part of the Matildas' build-up to Rio four years ago, only to be a late scratching from the squad under then-coach Alen Stajcic.

"For me personally, it would mean a lot because I was a part of that Olympic qualifying squad (for Rio) but I didn't go to the Olympics," Gielnik said.

"So it would be a first for me.

"And I think it'll be great for us going forward, especially coming off the back of the World Cup not being so successful for us.

"It's a bit of unfinished business."

It was the first time Gielnik had been to the World Cup, having also failed to make the cut for Canada in 2015.

"That was a big one for me. That was my own personal goal. And I think the same boat here with the Olympics," she said.

"Missing out more narrowly was a bit more painful for me.

"But I'll remember that feeling and I'll use it to my advantage to make sure that I'm not just a part of this team in a squad sense.

"I want to be really a part of it and (immerse) myself into the squad."
