The Senate election re-run in Western Australia has become an economic bonanza for small and large businesses.
The Australian Electoral Commission is expected to spend at least $23 million on the re-run election, which was the result of a botched ballot paper count at the 2013 election.
The High Court ruled the result void after 1370 ballot papers went missing during a recount which came down to a handful of votes.
The commission has promised to leave nothing to chance this time, engaging a wide range of consultants and using technology to ensure it gets the process right.
Among the largest contracts are just over $1.5 million for advertising and $654,000 for renting a number of premises including two owned by the Anglican Church.
Just over $180,000 will be spent on benchmark and tracking research by Ipsos Public Affairs to monitor the advertising.
Computer company Dell Australia won a $224,000 contract to roll out electronic copies of the electoral roll in selected polling places.
And Sydney-based IT company eHound was contracted at a cost of $21,000 for a web page to search for polling places around WA.
More than 6500 polling staff will be on hand, with one contract earning a Victorian company $12,000 for supplying purple bibs to identify polling officials.
Other contracts have been let for payroll systems, furniture, printing, language translation services, cartons and delivery of election materials to 13 overseas posts where people can vote.
The election will be a major logistical exercise for the commission, with 738 polling places open on election day this Saturday.
