The children of Australian farmer Mark Tromp have expressed relief that he is now safe, but will not give any details of their family trip to New South Wales that ended in mysterious circumstances.
Ella and Mitchell Tromp said they were "jumping for joy" when their missing father, Mark Tromp, was found in Wangaratta, in northern Victoria on Saturday, but an explanation for his disappearance is no clearer.
The bizarre case began last Monday with a family trip that left two members of the family in hospital with stress-related complaints.
Victoria Police are investigating the incident and the siblings told media at their home at Silvan, east of Melbourne, that they could not disclose any more information about the case.
They spoke to their father on Saturday night after he was taken to the Wangaratta police station.
The pair, referring to the situation as a "family matter", said they were unable to say what had sparked the case because police are still investigating.
"More than anything we're just happy that dad is alive and he's going to come back home - all of the family is going to come back home - and we can get back to normal," Ella Tromp said.
"It was all very confusing. I still feel confused. Mum and dad's minds weren't in the best places."
"It's hard to explain," Mitchell Tromp added.
Mitchell Tromp said at no time did he feel he was in danger. He said he just had to go with the family to see where they were going.
"It was tough to see your family like that and I've never seen anything like it," he said.
"But the main thing is they're okay now and everyone's safe, everyone's well, we can just go back to being a family again."
'Just like my dad'
Mark Tromp is being cared for by family and friends in Wangaratta and the siblings said they had spoken to him and he was keen to get back home and get to work.
"He was my dad, just like he always is," Mitchell Tromp said after speaking to his father on Saturday.
Jacoba Tromp remains in hospital and will see specialists on Monday but the pair were hopeful she would be released soon.
Another sister Rhiana is also in hospital in New South Wales and the siblings said her aunt was with her and her condition was improving every day.
Asked if he knew what sparked the incident, Mitchell Tromp said there were a few things but nothing he could state for sure "because I'm not certain".
"There's a few [things]... there's nothing that I know for sure but there are possible things but I can't say at this stage because I'm not certain," he told reporters.
"I can see why they [the public] want to know but it's a family matter and we just want the family to be back together and for everything to work itself out and I think it will."
