In the under 15 association match played at Morphett Vale on Saturday, Southern proved too strong all over the ground to run away comfortable winners by 78 points.
The match started well for Great Southern as they won the clearance through Sutcliffe, who came streaming through from half back to set up the first forward entry of the match.
It was not long until the creative Magor was on the end of a great pass and kicked the first goal of the game and the boys in red, blue and white were up and running.
However, it was the first and only time Great Southern would lead, as the powerful Southern unit went into full gear.
Magor, who was captain of the Great Southern team, was forced from the field with a knee injury and was never to return for the rest of the day and this deflated his team mates.
The Southern boys showed no compassion and run and supported each other in a great team display of football.
Southern booted the next 11 goals to split the game open and lay claim to the South Shield.
Spring, Lemmey, Visser, Bunworth, Hill, Flett, Stone, Schirmer and Kajanto combined to have Southern lead at quarter time, five straight goals to Great Southern 1-2 and at halftime 11-1 to 1-2.
Great Southern were insipid in the second quarter as the Southern team just pushed them aside to keep them scoreless and kick 6-1, to lead by 59 points at halftime.
In the third term Great Southern came out far more determined and proved they were a better side than shown in the first half.
Great Southern booted 2-2 to Southern's 3-1 to give the game a contest.
Great Southern were driven by Sutcliffe who went into the middle, Bottroff in ruck, Tom Wheaton, Hoeck, Rodrigues and Ker.
Southern on the other hand managed to reply with goals to Lemmey, Kathapoulis and Stone to at least steady the ship that became a little under pressure.
In the last term the game was once again a tough struggle for both teams, although Southern always did look the better side.
Visser kicked his third for the day and Flett and Brockhurst scored one each to cap off a great win for the Southern Football Association. Great Southern managed a solitary goal to the hard working Hoeck.
The final score was Southern 17-4 to Great Southern 4-4.
Best player for Great Southern and recipient of the Neville Miller medal was Josh Sutcliffe. Sutcliffe also won the South Adelaide award presented by Football Manager Warren Ploenges.
Best for Southern was Milan Spring. He was the catalyst to the team's win, especially early when the team needed him most and finished with two goals.
It is the second year in a row the Southern Football League has claimed the South Shield.
