The Greens are disappointed with the provisional result of the Western Australian Senate count.
Scrutineers have identified the result may have come down to a 14 vote margin and will likely require a recount before the final result is known.
Senator Ludlam has thanked the 124,000 people who voted Green in WA, and the Western Australian and national campaign teams for their work during the election campaign.
"In particular, I acknowledge Senator Christine Milne for her dedicated and tenacious leadership: the role of the Greens has never been more crucial than now," Senator Ludlam said.
The Greens will provide an update on the provisional count once scrutineers have assessed the grounds for a recount.
