Mark Tromp has apologised to the community and thanked police as he and his family recover from a bizarre road trip last week.
The 51-year-old and his wife, Jacoba, took their three adult children and fled their berry farm in Silvin, Victoria, last Monday out of one parent's growing feeling they were being watched and tracked.
In a statement released on Tuesday, Mr Tromp said he and his family hope to make sense of the "ordeal" and "return to normal life".
"I am conscious of the burden these events have placed upon our extended family, friends and the community resources devoted to our aid," Tromp said.
"Without reservation, I apologise for the hurt and concern caused by these events.
"On behalf of our family, I express deep gratitude to Victoria and New South Wales police, as well as the health care professionals who have looked after our physical and mental well-being.
"More than anything, my family and I need time to recover and receive appropriate assistance, including mental health services."
Mitchell Tromp, 25, told media last week he went on the trip to convince his parents to come home. They were banned from bringing technology with them so when it was discovered Mitchell took his phone with him, he was forced to throw it out the window.
Mitchell was the first to leave his family, with his sisters soon separating. Every family member was found in a different location across Victoria and New South Wales.
