Kerri Anne Bingley appeared in the Launceston Magistrates Court today on two counts of obtaining a financial advantage during 2009 to 2012. 

The former supermarket worker received more than $14,000 in overpayments from Centrelink due to under-declaring her income while working at Coles and Woolworths.

Her offending continued even as she was being prosecuted for the same offences she'd committed earlier.

Magistrate Reg Marron said she knew the consequences of under-reporting pay given he'd sentenced her to three months jail, wholly suspended, in 2010 for the same offence. 

He said there was ``no reasonable explanation or excuse'' for her latest offending which saw her lodge more than 50 false income statements to Centrelink. 

Mr Marron sentenced her to three months jail and ordered she serve a year probation once she was released. 

Bingley was taken in to custody in front of distraught friends and family in the court room.
