Western Australia's Senate election result will be declared on Wednesday, with the Greens and the Australian Sports Party still looking likely to miss out after a nail-biting race.
Australian Electoral Commission state manager Peter Kramer said the commission should be in a position to "press the button" for the formal vote count at 11am on Wednesday, with the result to be declared at noon.
Around 8 per cent of below-the-line votes remain to be entered into the AEC computer.
The ABC is projecting Labor's Louise Pratt will retain her place, alongside first-time candidate Zhenya Wang from the Palmer United Party.
They would join the Liberals' David Johnston and Michaelia Cash and Labor's Joe Bullock, all elected on first preferences, as well as Liberal Linda Reynolds, who is set to be elected relatively early in the preference count.
The result would see Greens Senator Scott Ludlam lose his seat and would also spell defeat for Wayne Dropulich of the Australian Sports Party.
The pair was on track to be elected until earlier this week when a late turnaround in the count saw them overtaken by Ms Pratt and Mr Wang.
Preference arrangements mean that Mr Ludlam cannot be re-elected if Mr Dropulich is eliminated at any stage of the counting process.
Mr Dropulich initially looked set to be elected with the help of a string of preference deals, despite attracting just 0.23 per cent of the primary vote.
