A close encounter with a kangaroo has left a far north Queensland psychologist a little jumpy.

Suzanne Habib was sitting at her desk in Atherton when the 1.5-metre marsupial came through the front door.

Dr Habib says confusion reigned.

"I called out, 'there's a kangaroo in my office'," she said.

"But then just as I called that out a couple of young guys just ran in off the street, and I thought it was their kangaroo, so I started yelling at them to get their kangaroo out of my office.

"Then I realised it wasn't their kangaroo; they had seen it come into my office and they had come to help me get it out."

The kangaroo eventually found its way out of Dr Habib's office.
