PROSERPINE shop owners say the closure of the ANZ could take a toll on business and place pressure on the older population.

The ANZ branch in Proserpine will close on Thursday, four months after the branch cut its opening hours.

This means residents will have to travel 20 minutes to the Cannonvale branch to do their banking.

Whitsunday Bakery owner Lorella Cassells has been banking with ANZ since 1986 and was disappointed the ANZ branch would permanently shut.

"It's going to impact me fairly severely," she said.

"It means I'll have to go to the beach at least twice a week to do my banking.

"On top of that, you've got to hold more cash, so you've got cash on your premises."

Ms Cassells said the bakery was a "cash business" and the closure would be felt across the community.

She was also concerned that if people had to travel to Airlie Beach to do their banking, they would also do their grocery shopping there.

"It has that domino effect as well where it takes people out of an already struggling town centre to go and do their shopping," she said.

"You're going to go when it's convenient."

The permanent closure was announced in August and ANZ district manager Rob Parker said customers "no longer look to branches for their everyday banking needs the way they once did" with more turning to phone and internet banking.

Mr Parker said measures would be put in place to help people who relied on the physical branch for banking, including working individually with "vulnerable customers" on alternative banking methods.

However, Ms Cassells was worried for the older Proserpine population and those who could not drive to Airlie Beach, a concern shared by Everything Office and More owner Tracey Cameron.

"I feel for them because it's a huge thing for them to have to go down to Cannonvale to do their banking," Ms Cameron said.

"They're limited on transport and the other thing with that is, it's a big thing for them to go through the process of switching banks if they want to.

"I just think it's a bit too much for them."

Ms Cameron said she wasn't surprised by the closure and that it would be a "real inconvenience" on her business.

Both Ms Cameron and Ms Cassells had looked into changing banks but said it would be too difficult with the current state of business.
