Since 2010, the two clubs have competed annually for the HMAS Sydney II Cup, honouring the 645 lives that were lost when the ship was sunk off the coast of Western Australia in November 1945.

[1][2] The Sydney Swans are the current holders of the cup, having defeated the Eagles by an equal club-record 171 points in Round 15, 2023.

[4] Future West Coast premiership ruckman (and now Sydney Swans coach) Dean Cox made his AFL debut in Round 2 of the 2001 season, in a close match which the Eagles lost by just 15 points.

Dual West Coast premiership player Glen Jakovich played his last AFL game after announcing his retirement in the lead-up to the match.

Jakovich kicked three goals as West Coast won only its third match of the season, defeating Sydney by 27 points but having to withstand a final-quarter Swans fightback to do so.

In a one-sided game at Telstra Stadium, a match played in thunderous conditions, Sydney thrashed West Coast by 41 points.

After leading most of the day, Sydney lost the replay of the preceding year's Grand Final when West Coast kicked 6 goals to 1 in the second half to win by 2 points at Subiaco Oval.

In what was literally a replay of the Grand Final, West Coast escaped with another one-point victory after Sydney managed to kick 7 goals to one in the second half at ANZ Stadium.

In round four, 2008, Barry Hall made headlines when he punched West Coast's Brent Staker in the jaw.

Another classic was played out in Round 11, 2008, when Sydney overturned a 36-point halftime deficit to win at Subiaco Oval, their first at the venue in any home-and-away season since 2001.

Round 17, 2015, saw West Coast end its eight-game losing streak against the Swans with a 52-point victory, its biggest win over the club since 2005.

However, the match was marred by constant booing from pro-Eagles fans towards Swans player Adam Goodes, who subsequently took leave from the club for one week following the incident.

Despite the West Coast Eagles being the reigning premiers, and the Sydney Swans suffering a decline in on-field performance, the Swans were able to defeat the Eagles by 45 points at the Sydney Cricket Ground, with Lance Franklin kicking a goal from the boundary line on the final siren.

In just their second meeting at Optus Stadium, the Swans made it two from two against the Eagles at the ground, kicking the first nine goals of the match and keeping the Eagles scoreless in the first quarter (the first time this had happened at home in club history) en route to a 63-point victory, which was achieved without injured forward Lance Franklin.

On 24 June 2023, the Swans recorded their highest score since 1987, and their equal-biggest victory, kicking 31.19 (205) in a 171-point thrashing of the West Coast Eagles at the Sydney Cricket Ground.
