The CEO, Paul Graham, was at NSW parliament House for a public relations event.
Ms Dalton took the opportunity to speak with him about the downgrading of the postal service at Coleambally, and other areas.
“I wanted a friendly conversation,” Ms Dalton said.
“I didn’t expect things to get that heated, but people are angry about the closure of post offices in rural Australia.”
Earlier this year, Australia Post decided to close Colembally’s Licensed Post Office, and set up a Community Postal Agency in a different location.
The change shifted postal operations into the local pharmacy, where mail is now sorted on a trestle table under a carport and long‑standing services have been lost.
The change also means a loss of dedicated PO boxes, and banking, bill payments, identity checks, passport services or parcel tracking.
The nearest full‑service post office is now 35km away in Darlington Point, a distance residents say is unmanageable for many older community members.
About 200 angry community members turned out in protest a fortnight ago, at a rally organised by Ms Dalton.
“Initially, Paul seemed like he wanted to shut down the discussion, but I wasn’t willing to walk away,” Ms Dalton said of her encounter with the company CEO.
“He said he was offended that I had mentioned his $3 million pay packet in a letter I wrote to him recently.
“I wasn’t trying to offend him. I was just stating facts.
“And quite frankly, I care a lot more about the feelings of the people of Coleambally than the hurt feelings of a CEO who thinks he can destroy rural Australia without someone calling him out.”
As the heated exchange progressed, some of which was caught on film, Mr Graham reportedly agreed to do everything he can to ensure Coleambally doesn’t lose access to postal services.
“Once he stopped accusing everyone of being rude and offending him, Mr Graham did agree to do what was necessary to ensure Coleambally keeps their postal services,” Ms Dalton said.
“So in the end, it was a pretty good chat, albeit a little fiery.
“The main thing is that the people of Coleambally will be protected, if Mr Graham keeps his word.”
