I think maybe the people behind the decision just figured that tigers are more popular with kids than koalas. Usually these sorts of changes strike me as just being a matter of appeal. That might also be the reason that say, Edison was dropped from the cast while Botley became more prominent- a robot is probably more interesting to kids than an insect. But that's just my hunch.
