As a child Tarni Brown would ask her parents – Collingwood champion Gavin and mother Kerry – if she could train with the Magpies development squads like her older brothers did.

So Kerry would ring Collingwood to ask on Tarni's behalf if she could train too, but the answer was always "no, girls aren't allowed". Gavin, now head of development at North Melbourne, was coaching at Carlton when Tarni was younger and she ended up barracking for the Blues.

But as of last week, Tarni finally got her wish. On Monday, at the Holden Centre, the Brown siblings all trained at Collingwood for the first time.
