Oliver Peterson: Australian correspondent on Anthony Albanese underperforming in the weekend by-election - Heather du Plessis-Allan Drive

Victorian voters in the outer-western suburban state seat of Werribee have voiced their feedback in this weekend's by-election - and they're not too happy with Labor's output.

Labor had held the state seat of Werribee since 1973, but this time, both major parties received less than 30 percent of the first-preference vote. 

Australian correspondent Oliver Peterson says this paints a concerning picture for Labor ahead of the upcoming federal election - as Albanese could lose seats in Victoria.
