ADELAIDE co-captain Erin Phillips wants to find out if her four-month-old twins fit inside the inaugural NAB AFL Women's premiership cup. 

The cross-code sensation will have her biggest supporters in the stands when the Crows take on the Brisbane Lions at Metricon Stadium on Saturday. 

Blake and Brooklyn stole the show as the Crows departed Adelaide Airport on Thursday morning.

"They're coming, they wouldn't miss this," Phillips said.

"I wouldn't live it down for the rest of my life if they grew up knowing they weren't at the first ever women's Grand Final and mum was playing.

"It's pretty special to have them with me and hopefully I can fit them in the cup if we win it."

Phillips' wife Tracy Gahan gave birth to the twins in November last year and they have quickly become part of the Crows' family.

"I feel like they've grown up with this group of girls," Phillips said.

"It's a sneaky ploy from us to bring them on the trip because we know they will get looked after and we will get a break. 

"They've got lots of aunties, we're one big family here."

Phillips, 31, has become one of the most influential players in the competition having come across from basketball. 

She's been short-listed for the AFLW Goal and Mark of the Year, while she will also be a major contender for the best and fairest.

Phillips is no stranger to playing in big games having won two WNBA championships, a world championship with the Australian Opals and an Olympic silver medal.

"It will be right up there, it would be an unbelievable feeling," Phillips said of winning the AFLW premiership.

"I'm trying not to compare it right now because I'd do it once we win." 

Crows coach Bec Goddard said Phillips' experience would be invaluable to the team. 

"Erin is a massive bonus to our team this week, of all weeks," Goddard said.

"Her football aside, which is obviously elite, she brings leadership, a calm head and knows what's required to get the job done and that filters through to the rest of the group." 

Crows defender Courtney Cramey travelled with the team, but will need to pass a concussion test before being cleared to play.

The Crows' Darwin-based players will also travel to the Gold Coast on Thursday before the team has its final training run on Friday. 

Phillips will return to the US for the WNBA season with Dallas before likely coming back next year to play for the Crows. 

"I definitely would like to keep playing as long as I can," she said. 

"I've had such an amazing time with these girls, so hopefully I can run around again next year."
