Sydney Swans co-captain Kieren Jack says his family issue is a private matter.

The family feud was made public this week ahead of Jack's 200th game.

Jack's mother Donna posted on Twitter on Monday that the midfielder had requested she and husband Garry not attend his milestone match as part of a feud lasting more than 12 months.

The premiership Swan refused to shy away from his scheduled media conference and pledged his support for his partner, and younger brother Brandon, who stood just metres from where Jack was speaking.

"I love [Charlotte] very much and I'm very proud of her," Jack said, describing the week's events as "unfortunate, and it hasn't been nice.

"I've been pretty disappointed with the way the situation has been played out in the public eye.

"My take on it is pretty clear, it's a private matter and my wish is for it to stay that way.

"What I have learnt through this is that family issues happen, but they need to remain private.

"I'm not going to get caught up in getting into a he-said-she-said, I think it's probably an immature approach.

"What I will say is that my priorities are firmly with my partner and my little brother, who I love and care for very much.

"As distressing as the events have been, the level of support we've given each other, on top of friends, other family members, teammates, and the Sydney Swans in general.

"It's highlighted to us how lucky we are that we've got those people in our lives."
