Unfortunately the man died at the scene and the state highway was closed for a few hours while police carried out their investigations. The woman was not injured and neither were the people in the ute.
"Police would like to hear from anyone who saw the couple walking along the road or may have given them a ride," Dickson said.
Dickson publicly acknowledged the help of the ambulance officer and neighbours.
"They showed great compassion and community care."
Dickson also issued a warning and said the state highway was not a place to walk or hitchhike particularly at night in heavy rain.
"It's hard for drivers to see in these conditions. If you have to hitch hike at night stay in well lit areas," Dickson said.
"The dangers of hitchhiking can be minimised by travelling during the day."
If anyone can help police they should ring 105, leave a message for Senior Sergeant Steve Dickson and include their contact details.
