'Hi Mum' family impersonation
Texts from a 'new number' pretending to be your child in trouble.
How it works
You get a WhatsApp or SMS from an unknown number: 'Hi Mum, I broke my phone, this is my new number.' Then they ask you to urgently pay a bill or transfer money because they can't access their banking.
Common scenarios to watch for
This scam shows up in several different shapes. Recognise the pattern, not just one message.
Classic 'Hi Mum' WhatsApp
Texts from 'a new number' claiming to be your child with a broken phone and an urgent bill that must be paid today.
"Hi Mum, my phone is broken, this is my temporary number. Can you pay $1,850 to this BSB? I'll repay tomorrow."
Red flags to spot
- Did the message come from an unknown number claiming to be family?
- Are they asking for an urgent money transfer for an unusual reason?
- Did they ask you not to tell other family members?
- Can you verify by calling the family member on their known number?
'Grandkid in jail' phone call
A panicked caller pretends to be your grandchild arrested overseas, then hands off to a 'lawyer' who demands urgent bail money.
"Nana it's me, I had an accident in Bali, I'm in trouble, the lawyer needs $6,000 today to bail me out — please don't tell Mum."
Red flags to spot
- Did the caller sound panicked and ask for secrecy?
- Were you quickly handed to a 'lawyer' demanding bail money?
- Are they asking for payment by wire, gift card, or crypto?
- Can you contact your grandchild directly through another family member?
Boss / payroll impersonation
Text from 'your manager' asks you to urgently buy gift cards for a client. Real manager never asked.
"It's Sarah — in back-to-backs. Please buy 6 x $200 Coles gift cards for a client gift and send the codes."
Red flags to spot
- Is the request for gift cards unusual for your workplace?
- Did the message come from a number or email you don't recognise?
- Are you being told the manager is 'in meetings' and can't be disturbed?
- Can you verify the request by calling your manager directly?
