Richmond father-son prospect Patrick Naish and potential No.1 pick Cameron Rayner are among nine Vic Metro players picked in the NAB AFL Under-18 All Australian team.

Naish finished his impressive carnival with 26 disposals in Metro's loss to the Allies on Wednesday, furthering his stocks as a possible first-round recruit for the Tigers, where his father Chris played 143 games. 

Rayner did no harm to his chances of being the first player picked across the carnival, kicking 12 goals across four matches and also showing his ability in the midfield. 

Also from Metro, Charlie Constable and Nick Coffield were selected in defence, Jack Higgins and Dylan Moore were picked in the forwards group, and Sam Hayes, Lachlan Fogarty and Joel Garner were named on the interchange. 

Hayes is the only two-time All Australian, having won selection as a bottom-ager last year.

Western Australia was excellent throughout its carnival, posting three wins from four games, and had four players named in the All Australian team, including Larke Medal winner Oscar Allen.

Allen kicked 11 goals in four games and was rewarded for his consistent championships by being named the best player in division one, while fellow WA prospects Sam Taylor, Brayden Ainsworth and Aaron Naughton also earned selection. 

Running backman Ben Paton, tall defender Oscar Clavarino and midfielders Paddy Dow and James Worpel were the Vic Country players picked. 

Exciting South Australian Izak Rankine was the only bottom-ager to make the team after a terrific championships, while forward/ruckman Callum Coleman-Jones and Harrison Petty also made it for SA. 

Jarrod Brander's excellent three-goal performance in the final round saw him break into the team, and he was joined by Allies teammates Zac Bailey in the forward line and Brayden Crossley in the ruck position.

Crossley is also a member of the Gold Coast SUNS Academy.

Vic Metro's Martin Allison was named All Australian coach, while Western Australia's Peter Sumich is assistant coach.

There are five players on the interchange to be in line with rules throughout the carnival, which saw all sides allowed five on the bench.
