With husband, former NRL player David Fifita looking on, a relieved Jade Robinson bowed her head as a magistrate told her she would not be jailed for fraudulently pocketing almost $50,000 from Centrelink when claiming to be a struggling single mum.

Gosford Local Court magistrate Jennifer Price on Thursday said she had decided to sentence Robinson - also known as Jade Fifita - to home detention despite the consistent and persistent way she had greedily rorted the system at taxpayers' expense.

Robinson, 26, used the single-parent Centrelink payments to buy clothes and a new car to try to keep up an outward appearance of success.

She pleaded guilty to two counts of receiving financial advantage from a commonwealth entity after she was found to have fraudulently received $48,500 in Centrelink benefits over almost five years.
