Summary information on Premiers, Government and Periods in Office in Queensland

Parliamentary government in Queensland is structured around the periods in office of premiers. A new government is formed whenever a new premier takes office (see commission), and the premier is responsible for the choice of ministers and the allocation of departmental responsibilities. For this reason, this website organizes summary information on governments around the periods that premiers and prime ministers have held office.

A parliamentary system of government requires that the premier, as head of government, maintains the support of a majority of members of the lower house of parliament which, in the case of Queensland, is the Legislative Assembly. The information in the three tables below and the notes which follow, summarizes the information held in the Australian Politics and Elections Database which relates to the duration of periods in office in Queensland from 1890, the party support for premiers, and information on the the number of ministers at the beginning of each premier’s period in office.

Periods in office

The period in office of a premier begins at the date on which he or she first takes office and continues until he or she is replaced by another premier. This period may include major changes to the ministry as well as minor cabinet shuffles and the addition or resignation of ministers. A period in office can span several elections and several changes to ministries.

The period in office of a premier ends when the premier loses or resigns office (or, very rarely, is dismissed by the governor). But the period can also be ended if there is a substantial change in the party composition of the premier's parliamentary support: the premier continues in office but the nature of the parliamentary support changes because of a split in the majority party or the break up of the governing coalition, and the formation of a new party grouping or coalition to support the premier.

Changes in the extent of parliamentary party support for a premier—changes from minority government to majority government (or the reverse)—do not affect the period in office of a premier. But the move from single party support for the premier to coalition support (or the reverse) does represent a new period in office.

Information on the periods in office of each Queensland premier can be found on the 'Periods in office' pages of this website; summary information is set out in the table and subject headings below:

Party support

Party support in this section refers to the parliamentary support a premier and government have in the Legislative Assembly to remain in office. For the period before 1890 in Queensland, this support was made up of factions and independent members of the Legislative Assembly sometimes called ministerialists. After 1890, the support was from political parties, although party discipline in parliament did not always operate with its current strictness until well into the 1900s.

Summary information on party support for premiers in the Queensland Legislative Assembly is set out in the table below. Table 2 replicates information on the start and end of periods in office listed in Table 1 but adds information on party support in the Queensland Legislative Assembly and at elections during each period in office.

Summary information on ministries

This database has limited information on the composition of ministries and can display only summary details of the first ministry in a period in office (see the 'Periods in office' section above). The first five columns of Table 3 repeat the information in the previous tables, and the following four give information about the number of ministers under various categories.
