Goals in each half from Paul Huntington and Jermaine Beckford claimed the three points to boost Leeds' promotion hopes.
McAllister said: "Being in the top six is a boost. I am delighted with this week's six points but not surprised. The players are wanting to win each game and to be offensive and positive."
With his own contractual position having been settled this week, McAllister added: "The players now know where they stand. They won't go into the summer wondering who the next guy will be and what sort of changes he will bring. It is now up to this group of players to show me they want me to be here for the future."
