Glee, the award-winning US musical series featuring Lea Michele and Jane Lynch, averaged a dismal 269,000 viewers in its 7.30pm time slot on Wednesday night.
Glee’s poor ratings are thought to have hurt the premiere of Mr & Mrs Murder in the Wednesday 8.30pm time slot.
The Aussie murder-mystery series, starring Shaun Micallef and Kat Stewart, averaged 782,000 viewers nationally - a solid result given the poor Glee lead-in figure.
Glee was crushed by Seven's My Kitchen Rules (1.76 million viewers) and Nine's The Block: All Stars (1.04 million).
"Glee is clearly not performing well in its current timeslot on Ten," a Ten spokesperson says.
Glee will be replaced on Ten by repeats of Modern Family.
Ten will be hoping the program change will boost Mr & Mrs Murder ratings in coming weeks.
