The Liberal Party has easily won the new Legislative Council seat of Prosser with its candidate Jane Howlett.
Ms Howlett finished with 8776 votes, ahead of Labor’s Janet Lambert with 7889 votes.
It has been a nail-biting wait for candidates since the election on May 5.
The outcome was finalised on Tuesday night after the distribution of preferences.
It came down to a three-way contest between Ms Howlett and Ms Lambert, who had both stood unsuccessfully at the recent State election, and Independent Steve Mav.
Ms Howlett finished on top after first preferences and was in front for the entire count.
She will be the inagural member for Prosser which stretches from Conara in the north to Port Arthur in the south and also includes the Glamorgan-Spring Bay municipality.
A big field of 13 candidates contested the election including three former MPs.
The Liberal Party will now have two members in the Upper House.
Ms Howlett could not be contacted for comment.
