Specialist teams will help NSW Police and their Belgian counterparts in the search for backpacker Theo Hayez, who went missing from Byron Bay a month ago.
Belgian investigators and specialist search teams will join NSW Police as efforts to locate missing backpacker Theo Hayez resume in Byron Bay.
The 18-year-old traveller was last seen on CCTV walking through the popular seaside NSW town after leaving the Cheeky Monkey's bar about 11pm on May 31.
There has been no sign of Theo since.
"Sadly we are no closer to knowing what happened to Theo but we will continue to work for the answers that his family so desperately need," Byron Bay's top cop Matthew Kehoe wrote on Facebook late last week.
The Detective Chief Inspector said searches are expected to resume in coming days after bad weather suspended operations over the last week.
Theo's parents, who arrived in Byron Bay earlier this month to join the search, held a special event at the Byron Bay Golf Club on Sunday to thank volunteers and police.
"Without all the support in Belgium and here in Australia I think we would be on the couch with tissues crying every day," said Theo's father, Laurent Hayez.
It's understood Belgian police landed in Australia on the weekend and have begun making contact with the family.
They are expected to accompany NSW Police as observers in searches around Byron Bay in coming weeks.
The two agencies have been working together since Theo's disappearance was reported in early June.
Police said specialist search teams are also expected to arrive today to help search the most rugged terrain around the popular holiday town.
Anyone with information is being urged to call Crimestoppers.
