THREE years after Townsville twins Bronte and Isabella Watter disappeared from school, their heartbroken father says the girls could be anywhere.
The twins' mother, Catherine Lee Watter - also known as Cassie - is accused of abducting the girls, who were then aged seven, from Hermit Park State School on April 4, 2014.
Dad Michael Watter, who has legal custody of the twins, relocated to the southeast from Townsville after sightings of the girls were reported in suburban Brisbane two years ago.
Mr Watter said he was now no longer confident his daughters are in the Brisbane area.
"We've haven't had the sort of information that puts them anywhere specific and … they could be anywhere," he said.
"Overseas is a possibility but I'm not really sure.
"We do still have people coming forward with potential sightings. It's not just about recognising the girls, it's about taking that next step and calling and reporting it."
Mrs Watter's car was found at Anderson Park in Pimlico shortly after the twins disappeared, with the girls' schoolbags still inside.
On April 7, 2014, The Family Court issued a recovery notice for the girls and police appealed for information from the public. In June that year, bank and social media records led detectives to the Strathpine and Everton Park areas and Mr Watter flew south to look for his daughters.
In September, 2014, Mr Watter moved to Brisbane, suspecting there was little chance his daughters were still in North Queensland.
Despite the police investigation continuing and Mr Watter renewing calls for help through the media to find the girls, no concrete information about their whereabouts has been revealed.
Mr Watter says he worries about his daughters' emotional and psychological wellbeing as the girls most likely do not have access to schooling, friends their own age and possibly even healthcare. He says Isabella shows a natural talent for sport while Bronte loves acting, plants and cooking.
Mr Watter said it was hard watching other parents spending time with their children.
"It's the little things that get to you like when you see little kids walking around with their parents and just doing normal things and I look and think my girls can't do that sort of stuff," he said.
"It affects me all the time."
