The plan follows emergencies such as near Cape Bridgewater in February when wildlife carers took 68 koalas to be rehabilitated after an incident on private property still under investigation.

Wildlife carers also assessed more than 200 animals in the fire-ravaged Budj Bim National Park and nearby Crawford River months earlier.

Animal Justice Party MP Andy Meddick said he secured $30,000 for Koroit's Mosswood Wildlife for the mobile unit in next week's state budget.

"Most people would remember the terrible events that happened down at Cape Bridgewater - Mosswood was the shelter that was able to step up and take the majority of koalas," Mr Meddick said.

"They have done incredible work."

The mobile facility will give wildlife vets access to medication, and transport cages at the scenes of emergencies and offer public education when not in use.

"When it's not needed it can go to schools and shopping centres to let people know what they can do when they come across injured wildlife," Mr Meddick said.

Mosswood Wildlife director Tracey Wilson said there were similar units in Melbourne but the shelter would have the first in the region.

"It will be purpose-built. It will be able to go out on site to disasters and work as a triage unit," Ms Wilson said.

She said the education component of the unit would play an important role to raise awareness of protecting habitats.

"It is all very well to rescue these animals and rehab them, if we don't have any environment for these animals to go back to there's very little point," Ms Wilson said.

"We would like to foster more engagement with the public and the government."

Just this week the shelter is caring for eight koala joeys, orphaned due to disease, dog attacks and one found abandoned. It can care for a maximum of about 35 koalas.

"Every wildlife rescuer is always stretched for funding," Ms Wilson said.

She said the mobile unit would cost about $100,000 to complete and needed further funding from non-government organisations.

Mr Meddick said he had pushed for the state government to invest more recurrent funding into wildlife care.

"These are usually one-off grants and they have to apply for grants every year. My ideal scenario is to see line items in the budget where wildlife care is funded," he said.
