William Tyrrell: Police Narrow Search To Small Area Of Bushland

It comes two weeks after police renewed their search for the missing toddler.

Police have narrowed their search for William Tyrrell to an area of dense bushland about 4 kilometres away from where he went missing more than three years ago.

They are now focused on a small 800 square metre area in Batar Creek, with the search expecting to last just two days.

Detectives identified the new search area as a result of investigations by Strike Force Rosann prior to undertaking the forensic search at Kendall.

"We're looking for anything that's foreign to the area, and anything that links to William's disappearance," said Detective Chief Inspector Gary Jubelin while addressing media on Wednesday.

Police are looking to speak to anyone who has seen anything unusual in the vicinity of Cedar Loggers Lane and Batar Creek Road around the time of William's disappearance, or even more recently.

The deputy state coroner is expected to visit the site in the coming days.

Police wouldn't confirm that they were hoping to find William in Batar Creek, but when pressed, Jubelin told Ten that they don't go searching new areas without good reason.

The bushland at Batar Creek is so dense that SES volunteer crews had to spend several hours chopping trees and clearing bush on Wednesday morning before the search was able to begin.

It comes two weeks after police commenced a forensic investigation of the four kilometre square area around William's grandmother's home in Kendall, northern NSW.

More than 50 officers have been combing the area since June 13, searching for evidence to prove that William's disappearance was due to human intervention, not misadventure.

"This extensive search is so that we can produce evidence to take into either a coroner's court or a criminal court," said Jubelin at the time.

William, who went missing on September 12, 2014, would have turned seven on Tuesday.

"If he were home, he would be opening his presents and running through the house laughing and playing with his new toys," his family said in a statement marking his birthday.

"But sadly, William is not at home. Today marks another heartbreaking year and another birthday without him."

The family said that it had been 1384 days since they last saw William, and that "we miss him every minute of every day... [but] especially today."

There is an unprecedented $1 million reward on offer for any information that leads to police to William.
