Rikki Colosimo, 35, was walking home from a party near Humpty Doo, a small town south-east of Darwin, when he was fatally struck by a car.

Police have charged a 37-year-old woman with his death, and allege she hit him while he was lying on the road and then sped away.

St Christopher's Church in Manuka was packed with friends, relatives and loved ones, who came together to celebrate Rikki's life.

He was remembered in moving eulogies by his sister Bobbie Murphy, brother Ben Colosimo and mother Sharon Cook, who spoke of his infectious sense of humour and love of life.

''By looking around the room and reading all of the kind words that have been sent to us, we know that we are truly blessed to have known him,'' Mrs Murphy said.

''His adventures took him all over the country, down many windy dirt tracks, and across great waters, but it led us all here today,'' she said.

''We are truly grateful that he has taken us all on his adventures, and led us into each other's hearts, where he will remain with us forever.''

Rikki moved to Darwin for plumbing work this year, but lived in Canberra for much of his life, going to school at St Edmund's College and Lake Tuggeranong.

He had a love for motorcycles, Harley-Davidsons in particular, and only just finished a charity ride from Uluru to Darwin on a $500 postie motorcycle.

That same postie bike, along with a group of Harleys, led Rikki's hearse away from the church on Wednesday.

Mourners dressed in fancy dress for the wake, something Mrs Murphy said her brother would have loved.
