From the article:

If a driver is reported once for refusing a service animal, they are suspended from the Uber driver app until they undergo additional education to understand their legal obligations.

A second report will generally result in permanent loss of access to the Uber driver app.

Drivers who breach the legal requirement to transport assistance animals in Victoria may be fined more than $1,900, lose their accreditation or, in some cases, face legal charges.

“Uber has tried to put things in place, but we don’t believe there has been a reduction in the frequency of issues — in fact we think there has been an escalation,” Blind Citizens Australia chief executive Sally Aurisch said.
She is calling for more law enforcement and transparency regarding refusal complaints, as well as service animal training in the preferred language of a driver.

“At the moment people stop complaining because they never find out what has happened, … there are penalties in place, although we don’t see them being enforced regularly.”

Still happening and getting worse despite existing driver penalties. The penalty needs to be escalated up the chain to include the company.
