Former Port Adelaide player Warren Tredrea is suing Channel 9 for almost $6 million in lost wages after a vaccination saga.

Tredrea is launching legal action in the Federal Court in the wake of his dismissal from Channel 9 after he refused to get the COVID-19 vaccination, with the news announced in January of this year.

The 43-year-old is claiming that he was unfairly dismissed from his $192,500 per year position, asking that the court make Channel 9 pay him the rest of his contract and also up to 30 years of his wage due to the "missed opportunity" of employment.

In a state of claim notice, Tredrea's legal team argued that the safety measures put in place by Channel 9 to stop the spread of COVID-19 were as, if not more, effective than vaccines.

โ€œThere are and were at all material times, other measures and control mechanisms in the workplace that were equally effective as, if not more effective than, vaccination,โ€ the court document reads.

At the time of Tredrea's dismissal, all employees of the company were required to be vaccinated against COVID-19 to be able to work on-site.

Both parties are set to enter mediation to prevent the case from going to a trial, which would be held in 2023.
