In total, he transferred $97,070 from his mother's bank account into his own.
Of that, $20,000 was a legitimate civil loan for a house deposit and $19,240 was either transferred to a cash card his mother used or was put towards their flights to the UK.
Today, Billington pleaded guilty to a representative charge of unlawfully obtaining $57,830 by deception.

A restorative justice conference between him and his mother will be considered ahead of sentencing.
