Chansey Paech represents Namatjira a vast electorate covering part of Alice Springs and communities further south.
Appearing before a Senate inquiry into the Federal Government's Community Development Program, Mr Paech said CDP was a "national shame".
Fines imposed under the program had left people with "no form of income or no stable income", he told the committee.
"You will often get calls from people in the community where they are stuck, they've been breached and they need money to buy the bare essentials," he said.
"People coming into town for a medical appointment are being breached and are unable to get back, so it's working in to help them [get] transportation home."
Mr Paech said he used his annual electorate allowance of $78,000 to help constituents, including giving them Coles and Woolworths gift cards to purchase food.
TheTurnbull Government has slapped more than 300,000 in fines on CDP participantsin two years.
People are stripped a day's Centrelink allowance if they miss work-for-the-dole activities or are late.
