T1/T2 workers are going to have to comply in customer facing roles. They can get reinstated to employment, but only if suitable roles out of public facing are possible. If the company had already tried reasonably to accommodate this then it's probably not going to be a successful challenge. That was part of the reasoning during the recent case in aged care, the worker refused to be vaccinate, she could not for-fill her role at home or in other areas of the business so dismissal was the only option. The commissioners upheld the decision.
In theory if you were a pilot for an airline, you could possibly be moved to 'freight only' flights removed from public contact if a position was vacant. But the position would have to be vacant and no one else displaced as a result etc etc, there would be no obligation to create a position.
