Western finished third in the South Australian Country Championship held in Murray Bridge last weekend.
Western started well on Saturday in picking up a thrilling one point success against Central, winning 5-3 (33) to 4-8 (32).
Matthew Crettenden kicked three goals in the victory.
However, Western fell to a 32-point defeat later in the day against Murray South East.
Western fought well but could not match the eventual champions in a 10-4 (64) to 5-2 (32) result.
That led to a battle against Eastern on Sunday to determine the bronze medalists in the championship, with Western winning by 47 points.
Western dominated from the outset, leading by three goals at quarter-time and extending the margin to 31 points by half-time.
Eastern was hampered by inaccurate kicking throughout the match as Western added five goals in the second half to secure a 13-10 (88) to 5-11 (41) result.
However, the weekend belonged to Murray South East.
The hosts achieved something unlike any other team before them in winning an SA Country Championship on their home deck.
The Saints dominated from the opening bounce against Southern Districts in the decider at Johnstone Park, Murray Bridge.
The ball rarely left their attacking 50 as they kicked 4-5 to 1-1 in the opening quarter.
Captain Brian Fenton endured a hard knock but remained on the field as Murray South East extended their lead to 30 points at the main break, 7-8 to 3-2.
The one-way traffic continued in the third, as the home side added three goals and as many behinds to the Blues' two points.
The runners-up gained a veneer of respectability by more than doubling their score in the final term, but Murray South East still ran over the top of them by a margin of 11-17 (83) to 6-7 (43).
This is a third championship for the home side, who defended their 2016 title and added to the one they took home in 2014.
Southern Districts had prevailed in 2015.
