Wardius kicked 149 majors in 49 Hume League matches, including 15 across three finals in 2023, before Greater Western Sydney signed the former academy member as a category B rookie. He had spent two years working on his family's farm in New South Wales beforehand. He ruptured an ACL late in the 2025 VFL season and is aiming to return late in 2026. He is yet to play a senior AFL game.
