Gday Ron,
It'll be Veda Advantage, who basically look after Credit Referencing in Australia.
You can pay about $30 and get a credit report sent to email almost straight away, or no fee and they will post it to her.
This will show who the debt is to, when it was put on there, possibly what it is for.
If it's not hers or it has been paid, she can get it amended/removed depending on what it is.
website is here Discover your credit history - My Credit File - Australia
There are quite often mistakes or incorrect info on these.
If you want a hand understanding it, or sorting it PM me or give me a buzz.
Cheers
