All the details you would give an employer or indeed, anyone to whom you would write a cheque are freely available these days.
However, they all mean diddly-squat without your password(s) or other security check.
Simply knowing your account number and BSB will NOT allow anyone to access your account..
Also, modern electronic banking uses heuristic algorithms to determine your spending habits.
Anything out-of the-ordinary is flagged and put on hold.
No system is perfect of course, but if by some happenstance your security codes are made public and you are fleeced, the bank will cover it for you.
Pretty darn quick in my experience!
Last year, some miscreant tried to charge a flight to Switzerland (?!) on my MC number.
The Commonwealth Bank caught it, refunded the charge, upped my credit rating and informed the local plods within 20 minutes.
Sacremento Police caught the twit in 2 hours.
Now he's doing
life in San Quentin!
Third Strike rule.
For
$1700.
What a putz.
