Emma Jane Watts, 42, of Sieben Drive, claimed $21,996.47 in an ongoing insurance scam against Australia Post involving seven offences from July, 2017 to January, 2020.

Watts also received $980 and two R.M Williams travel bags as part of a separate PayPal scam between August 21, 2019 and September 4, 2019. She bought the two bags for $980 but then requested a refund.

Watts was paid the money but altered the return barcode to indicate the items had been returned. The crime was detected by the original seller when the bags were not received.

Watts also attempted to claim insurance for undelivered parcels containing jewellery, that she never sent.

In each case she used the post office's self-service terminals to purchase insurance using fraudulent documents for items that did not exist.

On October 5, 2017, Watts purchased $3000 insurance and submitted a fake tax invoice for a $3250 solitaire diamond ring for which she was later paid $3011 in compensation when the package was not delivered.

She also waited several months before claiming two other payments worth $3535.27 from January 2017.

However, another $12,000 claimed in three offences on December 2017, February 2018, and January 21, 2019, were not paid as an investigation had already been launched.

Watts created a fake identity for some of the frauds when the extent of her crimes was uncovered by Australia Post working with police.

Solicitor Paul Johnson said Watts had some mental health issues that were detailed in a report.

"She has spent 20 year of her life inside, not so much locked up but afraid to go out," Mr Johnson said.

Mr Johnson said it was unknown if she had been diagnosed with agoraphobia but she has since been able to go out and became a victim herself after a large amount of money was allegedly stolen from her.

Mr Johnson said Watts committed the crimes after receiving payment for a legitimate claim.

Magistrate David Day convicted Watts for the eight offences and said it was a lot of money, there was planning involved and she crossed the custodial threshold.

"She's gone and kept chipping away at the post office," Mr Day said.

However, he sad the custodial sentence could be served in the community.

Mr Day gave her two-year Intensive Correction Orders with supervision, electronic monitoring, and treatment for her mental health. He also gave her a 15-month concurrent ICO for one offence and a three-year community correction order for another.
