West Australian Labor has still not picked a candidate for the Darling Range by-election but Premier Mark McGowan says he is confident the party will find someone suitable by the time nominations close on Friday.
Candidate Colleen Yates both entered and pulled out of the race last week after her LinkedIn profile proved to be misleading.
She had hoped to win back the seat for the government in the June 23 by-election, which was triggered by the resignation of disgraced Labor turned independent MP Barry Urban who fabricated parts of his educational and police service record.
"I'm very confident we can get a very good candidate," Mr McGowan told reporters on Wednesday.
He said the party would be selecting its candidate "very soon" and the vetting process would need to be comprehensive.
"I'm involved in all preselection matters and I'll be making my views known," the premier said.
The opposition has picked former upper house member Alyssa Hayden to challenge for the seat, which was held by the Liberal Party for more than 50 years until Mr Urban won with a 5.8 per cent margin in Labor's landslide election victory last year.
