Queensland has thrashed Northern Territory by 51 points to set up a fascinating showdown with Tasmania for the second division title in the 2005 NAB AFL under 18 championships.

The Scorpions 15.7 (97) defeated the Thunder 6.10 (46) in the second of the double-header played at Skilled Stadium on Tuesday. Queensland will now meet the Apple Isle on Saturday at Optus Oval.

After winning two of the past three division-two titles in 2002 and 2004, Northern Territory suffered its second consecutive 50-plus point defeat, after Tasmania thrashed it in the opening match on Saturday.

Queensland never looked in doubt, leading at every change, while the Territory was never in the hunt, after it produced just one goal in the first half.

The Scorpions had 10 separate goalkickers, while Glen Screech (three goals), Julian Kannis (two), Lee Spurr (two) and Jessie White (two) all multiple scorers.

Brad Howard was Queensland's leading possession winner, with 21 touches, while Austin Lucy, Spurr and Kannis were also among the Scorpions' best.

For the Northern Territory, Trevor Oliver continued his fine carnival, as he collected 21 disposals - his side's best - while Jethro Calma-Holt chipped in with two of the Thunder's six goals.

Queensland started in a blaze of glory, when slammed four in a row to gain a 22-point lead.

Austin Wonaeamirri broke through with Northern Territory's first for the match at the 17-minute mark of the first term, yet when Courtenay Dempsey added Queensland's fifth for the quarter, the Scorpions were back out to a 22-point lead at the first change.

Queensland dominated the first half and added a further three goals in the second term, as the Thunder was held scoreless during that period.

The Scorpions took a 40-point lead into half-time and by three quarter-time the match was well and truly over. Queensland had extended the margin to 47 points after adding three goals to two.

Although Northern Territory added three goals in the final term, which was its best for the match, it proved far too late, as Queensland added another four to its name and recorded its second win of the tournament.
