Cats down Magpies by one point in AFLW

Geelong have made a dream start to life in the AFLW with No. 1 draft pick Nina Morrison capping an astonishing debut by kicking the winning point in a thrilling victory over Collingwood.

Morrison, 18, had a game-high 22 possessions and also laid eight tackles in the 3.6 (24) to 3.5 (23) victory before 18,429 fans at GMHBA Stadium.

But it was her set shot which cannoned into the goalpost midway through the last term which was her most telling contribution.

"That was pretty exciting," said Morrison.

"At the time I was probably hoping for the goal but in the end the point was enough."

Cats coach Paul Hood was delighted with the contribution from his star teenager.

"It's pretty special; for your first game at AFLW level to have 22 disposals and work as hard as she did," he said.

"She copped some attention too, obviously the opposition were going to try and make it difficult for her.

"But she fought through that and I'm really pleased for her."

The Magpies were well served by cross-code star Ashleigh Brazill, who was brilliant all night in defence.

Brazill represents Collingwood in AFLW and Super Netball.

Former Australian Diamonds Test netballer Sharni Layton also showed some encouraging signs for the Magpies in her first AFLW game, forming a formidable ruck pairing with Erica Fowler.

The match began in blazing late-afternoon sunshine with the temperature still well over 30 degrees, although conditions became easier to contend with as the contest wore on.

The Magpies jumped out of the blocks with the first goal of the season from impressive key forward Sophie Alexander after a strong contested mark.

The Cats responded with the next three goals -- including two to Madeline Boyd -- as the home side held the Magpies scoreless in the second quarter.

The second half began badly for Collingwood, with Alexander stretchered off on a medicab after being concussed in a marking contest.

Shortly afterwards, teammate Jaimee Lambert also hobbled off after taking a painful knock to the shin.

But the former Bulldog was able to return to the fray and made her presence felt with a brilliant snapped goal off the outside of her right foot.

"She's one of the toughest players at our football club," said Magpies coach Wayne Siekman.

"She just gets up and goes again and gives her all.

"I reckon a lot of players in our team would look up to her and say 'well that's the model. If you went to be a really good footballer, hard and tough, you take Jaimee Lambert'."

Collingwood led by a point at three-quarter time but were held scoreless in a goalless final term, with the Cats edging ahead with points from Jordan Ivey and Morrison.
