A funeral service for Gary Tweddle, who died after going missing in the NSW bush, will be held in Sydney's northwest.
Mr Tweddle's body was recovered in the Blue Mountains last week by police.
The 23-year-old went missing from a work conference at the Fairmont Resort at Leura, west of Sydney, in the early hours of July 16.
According to a funeral notice posted on Tuesday, a service will be held on Friday in the northwest Sydney suburb of North Ryde.
"All are welcome to bring along a photo, memento or a messages to be put in a memory box that will be sent off with him," it reads.
Family and friends of Mr Tweddle have asked mourners to "wear colourful clothing to reflect Gary's exuberant personality".
They've also asked mourners to send donations, in lieu of flowers, to the volunteers who helped search for Mr Tweddle.
Cash donations will be split between all organisations that assisted in the search, the notice said.
