As the AEC generally does not know when an election will occur it must check and investigate the availability and suitability of polling places as part of its routine preparation. The AEC hired approximately 8,000 polling places for the conduct of the 2010 federal election. Due to the size of this preparation task, checking takes a number of months and possible polling place locations are refined and updated well in advance of each federal event. The AEC also actively seeks to secure polling places with access for people with disabilities in accordance with legislative requirements.

This is a simultaneous election for all members of both the House of Representatives and the Senate. Under the Constitution, the Governor-General may dissolve both the Senate and the House of Representatives at any time (except within the last six months of the House of Representatives term) provided the special circumstances as set out in s.57 of the Constitution are met.

Seat classification is generally based on the results for that seat from the last election.
Where a winning candidate received less than 56% of the two candidate preferred vote the seat is classified as 'marginal'; 56–60% is classified as 'fairly safe'; and more than 60% is considered 'safe'.
Anything more than an absolute majority (50% + 1 votes) is the swing required for the seat to change hands (for example: if a member holds a seat with 56% of the vote a swing of greater than 6% is required for the seat to change hands).
A writ is a document commanding an electoral officer to hold an election, and contains dates for the close of rolls, the close of nominations, the polling day and the return of the writ. The Governor-General issues the writs for House of Representatives elections and the State Governors issue writs for States' Senate elections.
