However, I was most surprised when the security dog pulled me up. The two lady handlers of the dog then inspected my bag after I opened it.

Finding only a small plastic bag that the supermarkets supply to put your fruit and vegetables in, I was asked if I had fruit in the bag and I replied that we had apples and mandarins in it yesterday.

The lady replied that was what the dog had smelt. I moved on to collect my baggage and I noted that it was pulled aside and the dog was sitting next to it.

Opening and unpacking my bag the handlers noticed a shopping bag and asked if I had fruit and vegetables in it.

Of course, I had over recent days and she explained that this is what the dog had smelt. I was quite amazed at the ability of this dog and the pleasant manner in the way the two lady handlers went about their job.

Congratulations to the government on this wonderful service to protect our primary industry from fruit fly and other pests.

I AGREE with Steve Rogers (The Examiner, August 12) let's clean up the Tamar.

I disagree with his dissembling on his use of many when describing scientists for and against climate change.

The overwhelming majority (98 per cent) agree on human-influenced climate change. Show us the facts that this is not true.

How easy is it for you to say M Chugg (The Examiner, August 12) that this is the greatest lie ever produced.

Yes, there are dissenters. You both number among them and based on the science you have a disproportionate amount to say.

Climate change is real.

Your denialism, your penchant for straw men, for example, unprecedented bush fires in the Arctic, are starting to wear pretty thin.

KENNETH Hayne AC QC handed his 900-plus page report to Federal Treasurer Frydenberg on February 1 this year.

It contained 76 recommendations alleging 19 cases of probable misconduct perpetrated by 22 entities. The report recommended the government refer 24 major Australian companies to the relevant regulator.

To date, the Morrison government has not publicly acted upon one single Hayne recommendation.

I have just read Adele Ferguson's very recently released book entitled Banking Bad.

This fascinating book is a timely reminder of both the extent and depth of the many instances of malpractice perpetrated by our once trusted banks and insurance companies. It similarly shines a strong light upon the thousands of woefully under-qualified, so-called, financial planners and advisers who have extorted millions upon millions of dollars from their unwitting and mostly hard-working victims.

Every perpetrator should, at least, be named and shamed as they have financially and physically ruined many of their victim's lives.

It's past time we heard just as to what is going on if anything.

Douglas Ross Robbins, Trevallyn.

We'd like to clarify some incorrect information about the Department of Human Services' income review system, following a recent letter published in The Examiner.

While automation facilitates data-matching, the oversight, review and debt-raising process is undertaken by our staff.

The suggestion that the process is fully automated is false as there is human involvement of our staff throughout the process.

Recovering over payments is a fundamental principle of our welfare system - when someone has a debt, the department is legally obliged to pursue recovery of that debt.

We have a dedicated team available to help people experiencing difficulties or who have concerns about their income review.

All correspondence includes a dedicated phone line available for people to call if they need additional support and advice.

If people are concerned, we strongly encourage them to talk with our trained staff.

These staff can step people through the process, provide tailored support, and connect people with other support staff such as social workers.

Data matching identifies discrepancies between income reported to Centrelink and what has been reported to the ATO.

Letters are then sent to customers asking them to provide information to explain this discrepancy.

These are not debt letters - no debt notice is issued until the person has been given ample opportunity to explain and resolve the discrepancy.

In 20 per cent of cases, people are either able to resolve the discrepancies themselves online or work with staff through the review process to resolve them, which means no debt is raised. The 20 per cent is not an error rate - it is the system functioning as it should.

If someone chooses not to engage with the department, we make a decision based on information they have previously provided and information from the Australian Taxation Office.

The Commonwealth Ombudsman has independently and exhaustively reviewed this program and found it is reasonable and appropriate to ask people to explain discrepancies identified from data-matching with other agencies.

If anyone is concerned or has any questions about their review, we encourage them to contact the dedicated phone line in their letter to discuss their situation.

Department of Human Services general manager Hank Jongen.
