are affiliated with the Labor Party and are also factionally aligned. The largest unions supporting the right faction are the Australian Workers' Union (AWU), the Shop, Distributive and Allied Employees' Association (SDA) and the Transport Workers Union (TWU). Important unions supporting the left include the Australian Manufacturing Workers Union (AMWU), United Workers Union, the Construction, Forestry, Maritime, Mining and Energy Union (CFMMEU) and the Community and Public Sector Union (CPSU). Preselections are usually conducted along factional lines, although sometimes a non-factional candidate will be given preferential treatment (this happened with Cheryl Kernot in 1998 and again with Peter Garrett in 2004). Deals between the factions to divide up the safe seats between them often take place. Preselections, particularly for safe Labor seats, can sometimes be strongly contested. A particularly fierce preselection sometimes gives rise to accusations of branch stacking (signing up large numbers of nominal party members to vote in preselection ballots), personation, multiple voting and, on occasions, fraudulent electoral enrolment. Trade unions were in the past accused of giving inflated membership figures to increase their influence over preselections, but party rules changes have stamped out this practice. Preselection results are sometimes challenged, and the National Executive is sometimes called on to arbitrate these disputes. Federal election results House of Representatives Donors For the 2015–2016 financial year, the top ten disclosed donors to the ALP were the Health Services Union NSW ($389,000), Village Roadshow ($257,000), Electrical Trades Union of Australia ($171,000), National Automotive Leasing and Salary Packaging Association ($153,000), Westfield Corporation ($150,000), Randazzo C&G Developments ($120,000), Macquarie Telecom ($113,000), Woodside Energy ($110,000), ANZ Bank ($100,000) and Ying Zhou ($100,000), all significantly lower than the 2014 donations by a Chinese donor Zi Chun Wang, which at $850,000 was the largest donation to any political party in the 2013-2014 financial year. At least one newspaper report queried the identity of this donor stating "news archive searches do not produce results for this name, suggesting Wang operates under another name". Another report mentions that in addition to a hotel and a travel agency, the donor's listed address at the Old Communist Cadres Activity Centre in Shijiazhuang houses several Chinese government entities, stating also that another publisher "tried many times without success" to contact the donor on the phone number listed in the donation return form. The Labor Party also receives undisclosed funding through several methods, such as "associated entities". John Curtin House, Industry
