The Kangaroos will ditch their royal blue and white stripes in favour of purple on Saturday to raise funds for the bone marrow failure research charity.

St Kilda captain Nick Riewoldt helped launch the foundation following his sister’s death in February 2015, aged 26.

Manson said the club’s senior footballers and netballers would don TWP-designed uniforms against Camperdown at Melville Oval to raise awareness about the condition.

The Kangaroos will use donation tins to collect money for the cause and will auction off a signed 2016 St Kilda guernsey at their AFL grand final function next month.

TWP – a Geelong-based design company – offered the uniforms to clubs as its way of promoting Maddie Riewoldt’s Vision.

“We are the first club outside metropolitan or Geelong clubs to do it,” Manson said.

“We are hoping Camperdown will want to make it an annual thing and do it every year, whether it’s in Camperdown or here.”

The final-round showdown has extra significance for the Magpies, who are locked in a battle with Cobden for a top-five spot.

They sit fifth on percentage but the bottom-placed Kangaroos could wreck their September plans.

The Bombers host third-ranked Warrnambool and must win by at least five more goals than the Pies to secure a finals spot.
