Both Gold Coast SUNS and the Sydney Swans are almost certain to progress to the qualifying finals of the NAB Cup after Saturday night's matches in Blacktown.

The GC SUNS are definitely through after they topped the group with a surprise thee-point win over the Swans and a 25-point victory over Greater Western Sydney, while John Longmire's men are unlikely to be tipped out of the second lucky loser spot.

St Kilda moved past Adelaide in the first lucky loser spot by virtue of its win and a draw on Friday night and the Swans, in turn, tipped the Crows into the NAB Challenge series with the superior percentage garnered from their 79-point thrashing of GWS.

With only one set of pool games remaining - between the evenly-matched Geelong, North Melbourne and the Western Bulldogs - it is highly unlikely the Swans will be eliminated.

This group was always likely to produce two qualifying finalists given the relative youth of the side fielded by GWS coach Kevin Sheedy, with the only surprise being GC SUNS and not the Swans as the pool winner.

The Swans ensured their progression to the next round of a competition previous coach Paul Roos never warmed to during his time in charge early on in proceedings.

Former Hawk Josh Kennedy starred for the Swans against the new kids on the block with three goals and 13 possessions in the whitewash that saw the Giants fail to register a goal.

Despite Hayden Jolly's last-gasp winner for the GC SUNS in the second game, the Swans were always going to advance on the back of their earlier triumph.

GWS threatened to complicate matters for Gold Coast in the final game when they held a surprise one-point lead at half time, but the Queenslanders assured their passage with a strong finish including two late goals to rookie Alik Magin.
