Police will also be interviewing the 22-year-old's father, who arrived in the country on Friday. The family released a new statement about her disappearance on Saturday, pleading for people to come forward with any sightings.
"Grace has never been out of contact with her family or friends for this length of time. As a family, this is an extremely difficult and emotional time for us all," they said.
"We are staying very positive in the search for our Grace and we all hope she returns home soon to her family."
Det Insp Scott Beard says officers are continuing to look through CCTV footage, which can take some time.
