After Griffith’s Daisy Armstrong claimed she was driven to emotional and financial ruin by con man Brett Joseph, she vowed to expose the Mudgee man’s exploits. 

Her public stance against Mr Joseph last week reached young Texan Stephanie Hoskins, 23, who was one month away from “marrying a monster”. 

Through a website set up by Ms Armstrong, the 23-year-old American discovered everything Mr Joseph told her was a lie.

“It has always been my only goal to protect others from going through the same horrible experience,” Ms Armstrong said. 

“I find it very concerning that he's been doing this kind of thing for 10 years and yet he still hasn't been charged or stopped.

“This girl would have already been terribly hurt by him but thankfully she found out the truth before the marriage.”

Ms Hoskins met the notorious Australian swindler on dating site Plenty of Fish in November, where Mr Joseph went by the name Brett Goodman and posed as a wealthy oil exploration worker.

Little did she know the man of her dreams was unemployed and accused of fleecing at least 50 Australian women out of their savings using fake aliases. 

After dating for only a few months, Mr Joseph proposed to her with a ring he claimed belonged to his “dead grandmother”.

The wedding date was set for March 31. 

A Current Affair featured the shocking story on Wednesday night, focusing on Ms Hoskins’ close call with the alleged con man. 

“My father is very ill, he has stage four cancer,” Ms Hoskins said.

“Brett used that to push the wedding along sooner.

'Without the help of Daisy, my friends, family, and police there is every chance I would be legally married right now to a monster,' she said.

Mr Joseph's plan unravelled when the couple went to the marriage registry and he was forced to reveal his real name.

A curious Ms Hoskins then Google searched Mr Joseph and discovered his troubling history – prompting her to sever ties with him.
