Walker will tour South Africa in January after starring for NSW at the national titles in Geelong last week.

He kicked four goals against Tasmania and Northern Territory and three against Queensland.

NSW coach Tim Sanson said Walker was unstoppable in the air.

“He had a really good week,” Sanson said.

“He was runner-up in the player of the carnival and gave us an option all week.”

NSW finished third after defeating Queensland on Saturday.

“It was a massive result for us,” Sanson said.

Albury’s Ben Kelly, Jacob Koschitzke and Jaara Moran, Lavington’s Aidan Johnson and Scots School Albury's Will Holmes also played at Geelong.
