WEST Coast is poised to target big man depth in the upcoming drafts after project ruckman Tony Olango was named among six delistings.

The Eagles confirmed senior-listed duo Luke Partington and Malcolm Karpany's departures on Monday after they were unable to crack an AFL appearance this season.

Olango, fellow rookies Callan England and Ryan Burrows, plus category B rookie Tarir Bayok, were also not offered new contracts.

None of that quartet made their debut for the Eagles.  

Olango, 20, hit the headlines in August after it was revealed he faced assault charges from an incident in Darwin the day before he was drafted last November.

The decision to part ways with the athletic 198cm NT Thunder product leaves West Coast skinny for tall timber.

The Eagles currently only have Nic Naitanui, who will miss most of 2019, premiership forward-ruck Nathan Vardy, recruit Tom Hickey and back-up Fraser McInnes as ruck options.  

WHO'S LEAVING YOUR CLUB? All the latest retirements and delistings

West Coast is tipped to consider drafting Zac Clarke after his impressive season for WAFL premiers Subiaco, but the 203cm ex-Docker has interest from several clubs.

Clarke, 28, was delisted by Fremantle after battling knee problems but bounced back in 2018 and averaged 39 hit-outs, 15.7 disposals and kicked 28 goals in 20 games.

South Australian product Partington is hopeful of a lifeline after averaging 25 disposals and a goal in 17 games for East Perth and finishing in a three-way tie for the Royals' best and fairest. 

The 21-year-old was West Coast's first pick at the 2015 NAB AFL Draft, and 28th overall, but only played six career games.

Karpany played six of his seven matches in 2017 and showed promise, highlighted by a three-goal performance against the Western Bulldogs.  

But the speedy 23-year-old – the 31st pick in the 2013 draft - battled a knee injury this season and managed only 10 WAFL appearances. 

The Eagles' delistings follows the retirements of veterans Mark LeCras and Eric Mackenzie.   

"I would particularly like to acknowledge Mally and Luke, who are both terrific young men and who have displayed great commitment and professionalism throughout their time with us," general manager of football Craig Vozzo said.

"Unfortunately, Mally’s 2018 season was cut short due to injury, whilst Luke’s efforts culminated in him tying for the 2018 East Perth best and fairest award. 

"This is always a very difficult time of the year as we finalise our list changes and on behalf of the club I would like to sincerely thank Mally, Luke, Tarir, Ryan, Tony and Cal for their contribution and wish them well with their future endeavours."
