Tracey Holmes, a reporter at the ABC, when she received a text message with a PIN code sent by Telstra.
She called Telstra to say she hadn't requested the code. Telstra said it appeared someone had attempted to access her phone account.
Tracey received another PIN code, and after calling Telstra again she was told five attempts had been made to access her information. After hanging up from that call, Tracey's mobile phone went to SOS mode and she couldn't make any further calls.
She called Telstra from an office phone, and they confirmed her mobile phone number had been transferred to another provider. "They said there was nothing they could do."
Tracey posted a video on Facebook that went viral and as many similar stories emerged.

$500 was taken from Candy's Westpac account with a cardless cash transaction, where an ATM withdrawal can be made using only a one-time pass code sent to a mobile phone.
The criminals also took $1,300 as a direct debit transaction.
"I was afraid that after four times, my phone number could be swiped again." Candy lost control of her phone four times in 13 months because of un-authorised porting.
She eventually changed her phone number but Vodafone tried to charge her $40 for this. And then an un-authorised port happened again.
"Vodafone suggested I put the mobile account into a different name but I have no one to do that for me. I don't think it's fair that I have to hide my identity."

"My friend's Facebook account was hacked and I received a message. I thought it was from him asking for my bank details.
The previous day I'd filled out paperwork to refinance my house. I'd had to put someone down as a referee, so it just sort of added up and made sense.
Suddenly, my phone reception turned to SOS only and I received a message that 'my porting' would take a few hours.
In the following weeks, the scammer accessed my bank accounts, transferred money from my home loan account into a newly created savings account, set up a global currency card to put money on an increased my credit card limit."
