Werriwa MP Chris Hayes wrote to the federal Communications Minister, Senator Stephen Conroy, three weeks before the post office was scheduled to cease trading. He hasn't received a reply yet, but the office is still closed.

Accusing Australia Post of ``turning its back on the community,'' Mr Hayes said the mall was ``becoming ghettoish'' and that closing the post office made it worse.

He said it affected young families, old people and those with disabilities who didn't have transport and who couldn't walk to the other side of the railway line to the other post office.

Mr Hayes said he knew it would take time to get a reply because Senator Conroy was ``quite busy'', but that Australia Post's reaction was disappointing.

He said Minto Mall had been built to be a shopping hub for the community.

``But now elderly people may have to pay for taxis to access the other post office, which is too expensive,'' Mr Hayes said.

Michael Trenaman, who works in Australia Post's network planning and strategy section, wrote to Campbelltown Council general manager Paul Tosi this month, telling him that Australia Post took into account access, delivery and the number and locations of post boxes.

``I would like to point out, though, that our other post office in Lincoln Street is barely a kilometre away,'' he wrote.

Mr Hayes said he hoped the post office would return to the Minto Mall area after Senator Conroy had read the letter he had sent him.

``The post office was well used even when many other business went into liquidation at the centre after it had become rundown,'' Mr Hayes said.

A spokesman for Savills Australia, the real estate agency that was in August given the task of selling Minto Mall, would not say whether the mall had been sold yet or whether it was under contract.

Mall owners Michael Kwok and Helen James have not returned any of the calls the Advertiser made since the controversy began more than a year ago.
