Divers will search waterways and a dam on a rural Queensland property as police ramp up the hunt for a young Aboriginal woman.

Investigators haven't ruled out suspicious circumstances in the disappearance of 20-year-old Bianca Gawne, who was last seen almost a week ago on the large, rural property she shares with her family at Tandur, south of Gympie.

A search of the property has so far failed to yield any clues and police say they're keeping an open mind about what might have happened to her.

The head of Gympie's Criminal Intelligence Branch says the length of time since Ms Gawne was last seen, heading to the area where she slept on the property, has sparked serious concerns.

He says police divers will search waterways on the boundary of the property, along with a dam.

"She was last seen leaving the shed area on the property and was walking back to her sleeping area ... and basically hasn't been seen by her family since," Gympie CIB officer in charge Robert Lowry has told reporters.

That was sometime between 7pm and 8pm last Wednesday. She was reported missing the next day.

Senior Sergeant Lowry says Ms Gawne's family is co-operating fully with police and there have been previous occasions when she's taken time away from them.

But he said those occasions were brief.

"Although there is a possibility that she has just wandered off to take time away from the family group, clearly there's also other possibilities of a suspicious nature," Mr Lowry said, but added: "Nothing at this stage is popping it's head up that way."

"Until she's found we'll be treating it with the urgency it deserves."

He said that if Ms Gawne was safe, she should make contact with authorities or trusted family members.

The 20-year-old's mobile phone and bank card have been found at the property.
