This paper contains a summary of the 1999 New South Wales election. It contains details of voting for all Legislative Assembly districts, as well as primary votes for the Legislative Council. A summary of the 1998 electoral redistribution is also included to assist in understanding the results, and there are several tables analysing the distribution of preferences in the Legislative Assembly, and the impact of optional preferential voting.

For each Legislative Assembly electorate, full details of primary and two-candidate preferred votes are provided. Where appropriate, a two-party preferred count is also provided. (See note on two-candidate and two-party preferred vote below). The format and calculations used in the electorate results are as follows.

First Count: The votes shown for each candidate are the total primary votes received. Percentage votes are calculated as a percentage of the formal vote for each electorate. Swing is calculated by subtracting the percentage vote received by a party at the previous election (adjusted for the new electoral boundaries) from the percentage received at the current election. Where the parties contesting the district differ from the previous election, ghost' candidates (indicated by "....") have been included representing candidates not contesting the current election. As a result, all primary swings add to zero, subject to rounding errors.

Final Count: Represents the two-candidate preferred count after the final distribution of preferences in an electorate. All votes that did not indicate a preference to the two remaining candidates are included in the total listed as Exhausted. Two-candidate preferred percentages are calculated by dividing the two-candidate preferred vote by the votes remaining in the count, that is the formal vote minus the exhausted vote. Two-candidate preferred swings are shown compared to the previous election, adjusted for the redistribution. Where the party composition of the final two candidates differ from the previous election (e.g. Albury), a ghost candidate appears, and three swing figures are shown. A two-party preferred count is also provided in these electorates.
