Michelle "Brumby" Tucker was a young prisoner first seen at Blackmoor Prison then transferred and became an inmate of Wentworth Detention Centre.
A misfit and a troublemaker. Real name Michelle, and the nickname (whose significance is obscure to an English audience) appears to derive from her habit of escaping at the slightest pretext.
She is first seen at Blackmoor when Rita Connors is transferred there (665) and is transferred to Wentworth after Blackmoor burns down.
Makes several attempts to escapes. She tried to escape by pretending to be Joyce Pringle.
Meg mentioned that she tried to escape from Barnhurst which means she was at Barnhurst before Blackmoor. Friend of Spike Marsh, but still there at the end (692).
