Born in 2001 on the Gold Coast, Walsh first attracted attention playing for the Burleigh Bears, where his athleticism and height gave him an edge in aerial contests. By 2019 he had secured a contract with the New Zealand Warriors, debuting as a teenager and instantly showcasing a blend of power and vision that belied his age. His early seasons were marked by rapid skill development, a growing fan base, and a reputation for decisive line breaks.
The 2022‑2023 period proved decisive: a high‑profile move to the Brisbane Broncos coincided with a surge in form, culminating in a State of Origin selection that cemented his status among Australia’s elite. Yet off‑field headlines—contract disputes and media scrutiny—tested his focus. Despite the turbulence, Walsh’s performances remained consistent, reinforcing the notion that his 181 cm frame is only part of the package; mental toughness now defines his legacy.
