POLICE believe missing Tweed brothers Jayden and Joseph Brady are deliberately avoiding being found.
During a major search of the Tallow Beach, Byron Bay area, police officers found a makeshift campsite.
They believe the brothers have been staying here with their father.
At least one of the boys was seen running from police into dense bushland.
It's understood police won't be continuing their search of the area, but will follow other lines of inquiry to find the brothers.
Police still have grave concerns for their welfare.
UPDATE, 5pm: REPORTS from the scene at Tallow Beach, Byron Bay, indicate that police may have sighted a child in the area where the search is underway for missing Tweed brothers Jayden and Joseph Brady.
The reports cannot be confirmed at this stage.
The police helicopter has left the search temporarily to refuel, and will return to continue the search.
POLICE have found a campsite near Tallow Beach, Byron Bay, they believe missing children Jayden and Joseph Brady were staying at.
Acting Superintendent for the Tweed/Byron LAC, Shane Cribb, said police had discovered a campsite within the search area.
The camp is in bushland, but close to Tallow Beach.
While he would not confirm what had been found at the campsite, he said police believed Jayden and Joseph had been staying there.
"We're confident that the boys have been camping there, although we're not sure about the father," Acting Supt Cribb said.
He also said that police did not believe that the boys' lives were in danger, describing the situation as a "welfare issue".
The SES and the Brunswick Valley VRA are helping with the search this afternoon.
It is expected that the search will continue until last light today, although Acting Supt Cribb said it was possible that the search would continue into the night.
He said the search area was difficult terrain, with some swampland.
Reported sightings of the father at Port Macquarie have been ruled out by the Acting Superintendent.
A GROUP of police are preparing to start searching the area around the Tallow Beach carpark at Byron Bay for missing Tweed children Jayden and Joseph Brady.
Inspector Bobbie Cullen said 11 police officers were currently on the ground and about to start the search, including a dog handler.
She said police had received several tip offs that the boys' father had been seen in the Tallow Beach area on a number of occasions over the past week.
On each occasion it was reported that he was alone.
Insp Cullen said it was hoped the sightings of the father would lead police to the boys.
Police are currently conducting a south to north land search, which will be followed by an east to west beach search.
A Brisbane Air Police helicopter is also assisting with the search.
A SEARCH is underway to find missing Tweed Heads boys, Jayden and Joseph Brady.
Tweed-Byron LAC Inspector Darren Steel said SES would assist police with the search, along Tallow Beach, along with a police helicopter from Brisbane.
MISSING Tweed Heads boys, Jayden and Joseph Brady, have disappeared before.
Tweed-Byron LAC acting superintendent Sean Cribb said the boys, 14 and 11, went missing about 12 months ago, for a longer period.
The father of the boys, Daniel Brady, was granted conditional bail yesterday, after facing Lismore Local Court for contravening an AVO which prevented access to the children.
Brady's bail conditions require him to remain living at his current address, believed to be in Mullumbimby.
Act. Supt. Shane Cribb said the two boys had still not been located as of Wednesday morning.
"We do believe there are people out there that do know the location of these two boys," Act. Supt Cribb said.
"We'd respectfully ask that those people come forward and provide police with that information so that we can return these boys back to their rightful house where they can be cared for appropriately."
Act. Supt. Cribb said there's so far no plans to begin an SES search for the boys, but urged anyone with information about their whereabouts to come forward.
"We believe the father will know the whereabouts of the two boys," he said.
"At this stage the father hasn't provided us any assistance in relation to the location of the children.
While Mr Brady, who was previously known to police, was arrested at Byron Bay Police Station on Monday for breaching an AVO, Act. Supt. Cribb couldn't elaborate on whether or not a custody dispute was at hand.
"The matter has been before the courts and I'll let the courts decide on that avenue," he said.
"Our main concern is not the father, our concern is the two children."
Act. Supt. Cribb said rumours of the children being held by a cult appeared to be false - but said all information they receive would be treated seriously.
"There's a number of rumours running around at the moment," he said.
"We're considering all options.
"Any 11-year-old and 14-year-old child that is not at their rightful home address, there's always going to be serious concerns.
"We're investigating all leads that we've got and all information we receive, we'll be investigating."
He said police had spoken to the mother, who was hugely concerned for the boys' welfare.
"As you'd appreciate, with any family missing their two children, the family's quite distraught," he said.
"We're maintaining contact with the family."
Act. Supt. Cribb said the Brady boys have four siblings.
He confirmed the two boys left their Tweed Heads home with their father about 3am Sunday; investigations are continuing to establish whether or not they left willingly.
Kingscliff resident Barry Kreigher believes he saw the boys last Friday morning at a bus stop outside Tweed Centro.
Mr Kreigher said the boys were with a dark-haired girl about the same age.
He said the children claimed to have just come from Brisbane, and were planning on catching a bus to Casino.
Mr Kreigher said fearing for their welfare, he gave the children $20 to buy some food.
UPDATE: Wednesday, 8.55am: Police are about to stage a press conference at Tweed Heads about the missing boys.
