The size of membership of a portfolio committee and the balance of Members between Government and non-Government Members is based on formulae set out in the Parliament of Queensland Act 2001 and depends on the political composition of the Legislative Assembly at the time.
Portfolio committees currently have five Government and two non-Government Members. The Ethics Committee has three Government and three non-Government Members. The Parliamentary Crime and Misconduct Committee has four Government and three non-Government Members.
The Leader of the House nominates the Government Members and the Leader of the Opposition nominates the non-Government Members. The Chair of a committee is nominated by the Leader of the House. The Legislative Assembly, by resolution, approves these nominations.
