All Australians Chelsea Randall and Sarah Perkins have committed to the Crows for AFLW 2018.

Randall, 25, has made an enormous impact since joining the Club as a marquee signing last year.

Named co-captain of the Crows, the inspirational utility won the Crows Players’ Player award and was voted Most Courageous by her peers across the AFL Women’s Competition.

Randall finished second behind co-captain Erin Phillips in the voting for the best player on the ground in the Club’s historic AFL Women’s Grand Final win over the Brisbane Lions.

Playing in defence with stints in the midfield, the West Australian ranked second in the League for intercept marks and top 10 for inside 50ms, tackles and contested possessions at the end of the home and away season.

Randall said she was excited to sign on with the Crows.

“I’ve loved this Club since I walked in the door," Randall said.

"Adelaide is like home to me now. It was such an honour to, alongside Erin Phillips, lead the Club and an amazing group of women to the first-ever AFLW premiership.

“We have a really strong culture. We’re already looking forward to 2018 and building on the success of this year.”

Perkins, 23, was one of the success stories of the inaugural AFLW Competition.

The Victorian was snapped up by the Crows as a Free Agent after being overlooked in the AFLW Draft.

The forward developed cult-hero status for her clever play, goal celebrations and fun-loving nature.

She topped the Crows’ goalkicking and finished second in the League with 11 goals.

Perkins equalled the competition record of four goals in a dominant display against Collingwood in the last round to help propel the Crows into the Grand Final.

She took eight contested marks in the home and away season (ranked equal-fourth in AFLW), and led the Crows for score assists alongside Phillips.

Perkins was just as effective without the footy, leading the League in forward 50m tackles. She also forced the second-most turnovers of any player during the season.

Like Randall, Perkins said she was settled in South Australia.

“Things have worked out better than I could have imagined at Adelaide and I’m thrilled to re-sign with the Club,” Perkins said.

“I’m really happy that I moved, I’ve found my passion for football again and I can’t wait for the second season of the AFLW.”

The AFLW player signing and Trade Period runs until Friday, May 26. The Crows will announce more player re-signings across the course of the next week.

For Season 2018, AFLW squads will be extended to 30 which includes 27 senior-listed players and three rookies.

Rookies must either be under 21 years of age on January 1, 2018, or not have played Australian Football or been part of an AFL high performance program in the three years prior to May 1, 2017.

A Free Agency period follows the signing and Trade Period, allowing players who played in 2017 but were not re-signed the opportunity to be picked up by another club.

Players who are still unsigned can then nominate for the draft on October 18.
