Dehaney was part of the Jamaican Sunshine Girls’ successful Commonwealth Games campaign, where she claimed silver and recorded her 50th international appearance.
The 29-year-old first joined the Club in 2024 and has since played 48 games in the green dress, alongside 119 National League appearances.
Dehaney said her decision to return was driven by her belief in the team’s potential to contend for the title.
“Not having the ability to win a premiership is one thing but knowing we have it and haven’t quite achieved what we’re capable of has been weighing on me,” she said.
“The opportunity to go all the way with this defensive group is something I'm genuinely excited about. We know what we’re capable of, and I truly believe there’s something special ahead of us.
“Returning was always the goal. To compete alongside this group and play in front of the biggest, loudest and most supportive crowd in the competition is an opportunity I am excited to embrace.”
West Coast Fever General Manager Sara Francis-Bayman said the Club shared Dehaney’s determination to compete for the title next year.
“Kadie-Ann is a vital part of our defensive unit, her defence of the shot and rebounding capabilities are elite, and she stepped up to being a 60-minute player for us last season,” she said.
“Her unique skillset as well as her personality and humour are incredibly important to our Club.
