One of the two parts of the Australian referendum, 1967 was a question relating to the relative number of members in each house of the Australian Parliament − the so-called "nexus". Section 24 of the Australian Constitution requires that the number of members in the House of Representatives be, as nearly as possible, no more than twice the number of members in the Senate.

The most important effect of the "nexus" in the Australian Constitution is to prevent the dilution of the collective voting power of the Senate, which represents the Australian States equally, in any Joint Sitting of both houses following a double dissolution election. The nexus ensures that Senators will always have about one-third of the votes in a Joint Sitting, and Members of the House of Representatives about two-thirds.
