The Electoral Commission is hiring more than 18,000 people to help out during the election in September.
It is advertising for 3000 headquarters staff to help with details such as vote counting, as well as for 15,500 election-day staff - all paid roles.
Almost 200 managers and trainers have also already been hired.
A spokeswoman for the commission said it had received 16,500 responses to advertisements by June 6.
"While most applications come from people who have done these roles before - who come from all walks of life and largely reflect the communities they will serve - we're always looking for new people to join the team," she said.
The commission wanted to see more young people involved and said staff would need to ensure they behaved in a politically neutral way.
Anyone who had been involved in furthering the interests of any parties, candidates or issues would be excluded.
The spokeswoman said staff were needed to help with jobs including issuing voting papers, managing voting places, processing and counting votes, and interpreting.
Pay ranged from $370 a day for mobile managers to $18 an hour for interpreters.
The total cost of hiring the staff was about $11.5m.
