Yes. The story here is straight from Associated Press, but I looked around and found a few more details in a Telegraph article:

But he woman’s doctor told police that the defendant had tested positive with a rapid test before telling him that she “certainly won’t let herself be locked up” after the result.

Instead she left her apartment and talked to people without a mask, ignoring her mandatory quarantine and positive test.

Note they say MANDATORY quarantine. At the end of the article they explain that Austria's far right party, Freedom Party, is hyper-anti-vax, expected to win upcoming elections:

Its manifesto has promised a pardon for anyone convicted of breaching coronavirus rules and to repay any fines imposed during the pandemic.

The manifesto says coronavirus regulations were encroachments on fundamental rights “accompanied by unprecedented indoctrination and brainwashing.”
