Nationals leader Peter Ryan made the pledge outside Wimmera Uniting Care's Baillie Street premises last week and vowed to lobby the Federal Government to match its commitment.

But Labor refused to commit to the project, with Mental Health Minister Lisa Neville releasing a statement saying the government already supported Wimmera Uniting Care with financial support of 'about $4.3 million a year'.

Wimmera Uniting Care chief executive Wendy Middleton said Labor should support the project because it would help the organisation deliver many of the government's regional development and social services.

Board chairman Roy Henwood said Wimmera Uniting Care had outdated facilities and was being forced to operate from multiple sites.

He said it was important the State Government recognised the value of Wimmera Uniting Care's work with a funding commitment.

"Without Wimmera Uniting Care at least 8000 people annually could fall through the cracks," he said.

"I cannot stress enough that the work of our staff to deliver programs in the areas of child, youth and family care, mental health, disability and housing is vital to this community."

Labor candidate for Lowan Mandy Kirsopp defended her party's policy last week, labelling it a 'responsible economic decision'.

She said Labor would be in a position to make a 'range' of funding announcements to support regional communities if it was returned to power when voters went to the polls tomorrow.

A spokeswoman for Mental Health Minister Lisa Neville released the following response yesterday:

"We understand Wimmera Uniting Care provides a range of valuable services across the region and that's why Labor will continue to work closely with them on planning for the future needs of the local community."
