(1) For the purposes of each redistribution of a State, the Electoral Commissioner shall, by instrument in writing, determine, in accordance with subsection (2), the redistribution quota for the State.
(2) As soon as practicable after the redistribution commences, the redistribution quota for a State shall be determined by the Electoral Commissioner by dividing the number, as nearly as can be ascertained by him or her, of electors enrolled in the State at the end of the day on which the redistribution commenced by the number of members of the House of Representatives to be chosen in the State at a general election and:
(a) if the number so obtained includes a fraction that is less than one - half--reducing that number to the nearest whole number; or
(b) if the number so obtained includes a fraction that is one - half or more--increasing that number to the nearest whole number.
Note: This section rounds the number of electors for a State or Territory. Section 48 rounds the number of members for a State or Territory (and the method of rounding for Territories under that section may be different).
