Greens senators have come out to defend the leadership of Richard Di Natale after an attack from one of their own.

Senator Lee Rhiannon used a television interview on Sunday to express her disappointment in the party's leader.

It followed her exclusion by the party room from discussion on contentious legislation over her campaigning on schools funding.

Her Tasmanian colleague Peter Whish-Wilson says Senator Rhiannon was out of line.

"We all support Senator Di Natale as our leader, and if Senator Rhiannon has a problem with that, then she needs to make it very clear she is the odd person out in this regard," he told ABC radio on Monday.

"There is no leadership issue in the party room."

Co-deputy leader Larissa Waters said she was proud of the job being done by Senator Di Natale.

"Honest, decent, and policy before politics," was how she described her leader on Twitter.

Senator Rhiannon on Sunday also said it was time members had a say in who leads the party - something Senator Di Natale put to national conference last year.
