The Swans will be primed for a return to the Grand Final after a week off following their hard-fought qualifying final win over Fremantle.
But the Kangaroos will carry plenty of confidence into the meeting, and not just because of their two exciting finals victories. When the Roos and Swans met in round four at the SCG, North Melbourne won by 43 points.

The second preliminary final, between Hawthorn and Port Adelaide, will be played at the MCG in twilight timeslot starting at 4.45pm AEDT.
The start time will ensure the Power are able to travel back to Adelaide on Saturday evening following the game after the AFL worked closely with partner airline Virgin to confirm flight availability.
Hawthorn will enter the game favourites after its week off and strong qualifying final win over Geelong.
But Port Adelaide has regained its early-season form and, like the Kangaroos, have strong self-belief after brilliant elimination and semi-final wins.
