The council withdrew a grant of $25,000 for the $150,000 unit when it made decisions on its long-term plan last month.
However, chairman Tony Wood revealed on Wednesday the Lions Foundation had this week stepped into the breach with a $30,000 grant.
Mr Wood said he was "disappointed" with the council decision to withdraw from the proposal, which had been a joint venture with Civil Defence.
However, he said he "understood" the budget constraints with which the council was faced.
The group needed a further $80,000 to equip the mobile truck unit with appropriate communications and satellite capabilities needed in remote locations, Mr Wood said.
"We are waiting for other grant applications at the moment," Mr Wood said.
"We will continue with our fundraising, and I am confident that we can create this for the community."
