The Australian Electoral Commission (AEC) says it has implemented key practical recommendations of the Keelty investigation into the West Australian Senate election bungle.
But improving the AEC's training and culture will take some time, according to acting electoral commissioner Tom Rogers.
Voters in the state learnt on Friday that they will head back to the polls on April 5, the fourth time they've had to do so in just over twelve months.
The AEC has apologised profusely for the missing ballot papers that brought about the election re-run, while Commissioner Ed Killestyn and WA electoral officer Peter Kramer resigned over the controversy last week.
Former federal police chief Mick Keelty concluded there were significant failures in some of the ways ballot papers were handled, moved and stored.
But the AEC was focused on delivering a successful poll, Mr Rogers said.
"This is one of the most significant issues that we've dealt with in our 30 year history, so the import of this is not lost on me or the other executives," he told reporters.
Mr Rogers said many of the improvements were behind-the-scenes, but voters would note AEC employees wearing bright purple bibs, not just the badges they previously wore.
Parcelling, labelling and transporting of ballot papers was a key focus, Mr Rogers said.
"A lot of difference is going to be applied to how we actually package, parcel and move the materials, and particularly that chain of custody - who has them at any point in time, who was signing for those, how they are labelled and then how we move them.
"In the long term, we'll probably start considering whether or not the long-term storage of ballot papers is something we want to do.
"We've had a number of meetings with industry about the movement and storage of ballot papers, and we're implementing some changes around that, particularly with packaging, direction and control, and we're going to have that in place for this election."
He said many of the new processes had been trialled at the recent Griffith by-election.
