She and Brad announced their split in October 2015 after eight years of marriage.

Earlier this year, Pia opened up about the difficulties her children faced when she moved away from her ex-husband. 

She told Insider there had been 'hard times and some sad times' for the boys, who moved with her to Sydney so she could film Home And Away. 

'But all in all they've made some really good friends and integrated into their own little school teams,' she added.
