Collie moved to sixth spot on the South West Football League ladder following a devastating performance in Round 12.
Recovering from a sluggish start to the season, the side turned heads with wins over Donnybrook, Eaton, and South Bunbury.
Carey Park recently slipped out of the top five after three consecutive losses.
Both sides came together for the 2019 Indigenous Recognition Game at the Collie Recreation Ground, on Sunday afternoon.
Indigenous community members and club representatives addressed the players, coaches, and crowd prior to the opening bouncedown.
The Panthers' campaign started poorly, with Jeffrey Carter being knocked down and taken off.
Players at both ends were greatly affected by the wind and rain.
Following a few near misses, Collie's Rhys Chappell lined up to kick the game's first goal from 30 metres out.
The Eagles set up several chances, before Carey Park picked up steam and moved the ball up forward.
Taking a nice mark in front of goal, Talan Michael posted the home side's second midway through the first quarter.
Play then stalled, after both sides became involved in a nasty brawl near the boundary line.
Ahead by 11 at quarter time, Collie was caught off-guard by the visitors early in the second term.
Much to Carey Park's dismay, Eagle Alex Tweedie booted the first of his two goals just before half time.
Holding a 20-point lead at the main break, the home side sought to put the game out of reach.
Shortly after Tweedie's second, Jayce Fontana moved up from the backline to boot the Eagles' fifth.
Following several miss-kicks and turnovers, the Panthers celebrated as Viv Blurton posted the side's first and only goal.
Collie later extended its lead from 31 at three quarter time to 84 at the final siren.
Marlon Johns booted two goals in the fourth term, before Jeffrey Smith notched up his second in style.
Goals from Mathew Michael, Blake Shanahan, Jack Dye, and Kolbee Fleay helped the Eagles to a 13.20 (98) to 1.8 (14) win.
After Landmark Round, the side will face off against Busselton in Round 13 at Bovell Park.
Harvey-Brunswick-Leschenault continued its unbeaten run with a 11.10 (76) to 3.4 (22) win over Augusta-Margaret River.
The Boomers retained second after beating ninth-placed Busselton, 17.5 (107) to 7.3 (45).
Losing to South Bunbury 11.10 (76) to 7.6 (48), the Harvey Bulls' season sunk to a whole new low.
Donnybrook overcame Bunbury, 12.5 (77) to 5.11 (41), in their Grand Final rematch at VC Mitchell Park.
