The ALP may have lost the election, but it has managed to hold onto the final undeclared Victorian seat of McEwen.
Counting is complete in the central Victorian seat and Labor MP Rob Mitchell has held onto it by about 345 votes.
Mr Mitchell will let the Australian Electoral Commission officially declare the seat, but said "it is just a formality now".
His Liberal opponent Donna Petrovich has contacted him and released a statement conceding defeat.
"It has been a long, challenging and extremely close count since election day, however as the final ballots are tallied I concede that Labor has retained the seat," she said in the statement.
