The actress previously opened up to news.com.au about how strange it was leaving the island.
'Even looking out of a window is overwhelming. The first time I heard a song I burst into tears.'
Pia recently faced heavy backlash from fans after she was accused of cheating on one of the show’s challenges.
The contestants were challenged to hang onto a bar for 90 minutes, first with both hands, then with two. In the final moments, Simon slipped off taking himself out of the challenge and soon after Luke did the same. However, in-between Simon and Luke bowing out of the challenge, eagle-eyed viewers spotted Pia appearing to grip the bar with both hands.
Taking to Instagram, Pia - who recently opened up about the shock medical condition she was diagnosed with during filming - attempted to clear up the controversy.
"In regards to the edit showing me apparently changing arms," she wrote, "I was changing them throughout the challenge when it was 2 arms to give each one a rest. I can only assume vision came from that period of the challenge."
