This supports the view that it is the Senate ballot paper that encourages the use of 'I' only voting at House of Representatives elections. • Infonnal voting for Wills at the 1990 election is not available. However, despite there being 22 candidates, the infotmal voting did not increase, and the rate of infonnal votes with defective numbering was still lower than at other elections. • The data for Werriwa has been accumulated by the author to match the categories used in previous research. The informal vote increased at the by-election, but it should be noted that the Liberal Party did not nominate a candidate. • While the rate of Defective Numbering ballots fell to 45.3%, three~warters of these were ballots classified by the AEC as 'Non-sequential'. • In Werriwa, the proportion of 'I' only ballot papers fell from 36.9% to 9.1 %, in raw numbers from 2482 to 927. • The nwnbcr ofvotes marked with ticks and crosses fell from 14.6% to 4.8%, overall from 983 to 489 ballots. • The evidence in the above table suggests that the rate of informal voting is lower at by­ elections because there is no Senate ballot paper to confuse voters, the the absence of a major party candidate may increase the level of informal voting. 2007 JSCEM - Appearance by Antony Green 3 Informal Voling at Australian Elections NEW SOUTH WALES Informal Voting at Federal Elections in NSW 1990-2007 Candidates %.Informal Vote by Number of Candidates per electorate 1990 1993 1996 1998 2001 2004 2007 2 2.4 3 2.7 2.9 4 2.5 2.6 3.9 4.2 4.7 5.9 5 2.8 2.7 3.4 4.6 3.5 5.5 4.8 6 3.2 3.6 3.4 3.0 4.2 5.0 4.9 7 3.9 3.3 3.4 4.3 4.7 5.6 4.7 8 2.8 3.2 3.2 3.9 6.3 6.7 4.7 9 3.4 4.4 4.1 7.0 6.7 5.8 10 7.0 3.7 5.0 4.6 6.2 6.3 5.\ 1\ 4.4 4.4 5.3 6.8 4.9 12 6.0 7.4 \3 5.7 6.2 14 11.8 Overall Informality House 3.\ 3.\ 3.6 4.0 5.4 6.\ 5.0 Senate 4.2 2.7 3.8 3.3 3.5 3.5 Electorates 5\ 50 50 50 50 50 49 Candidates per seat 5.6 6.2 6.4 7.8 7.9 7.6 7.0 Source: Australian Electoral Conunission published results, calculations by author.
