"When I married, my husband joined and then my two sons. Over the past two years it started becoming expensive and we started dropping the plans down. Then we dropped my husband and then my two sons and after a year and more increases I decided to drop mine," she said, adding that she had made only one claim on the policy.
Vanessa Crabb said that at 55 her premiums were starting to rise.
"I have been told by friends over 65 that once they reached that age their premiums soared. Many of us have paid thousands over many years and not claimed anything like those in costs. So the question remains: over the life of the membership what amount has been claimed versus paid?" she asked.
Herald readers were responding after Creagh said the society was penalising its older members and the annual $5000 in fees he paid for himself and his wife was exorbitant and unethical.
Another Southern Cross member said he had been with the society for more than half a century.
"My premiums increase annually. Many of my pensioner friends have had to resign as they are unable to afford the premiums [if they rely mainly] on the pension. This creates an additional burden on the public system."
Under pressure from shareholder advocate and accountant Bruce Sheppard, the society has agreed to a premium review.
A spokeswoman defended the society.
"While we understand the Rev Creagh's concerns, he has received very good value from his health insurance and our data shows that this is true for many older members."
