Mary, the Tasmanian devil, escaped from her enclosure on the Gold Coast last Tuesday.
A rescue team of nearly 20 people has searched on foot day and night, using sniffer dogs and a thermal drone.
What's next?
Wildlife carers have thanked residents for supplying video of sightings.
Carers are honing search efforts to recover a two-year-old Tasmanian devil on the loose in a leafy Gold Coast suburb.
The devil, named Mary, has been missing for a week after breaching her enclosure by making an "abnormally large leap" last Tuesday, according to Paradise Country wildlife park staff.
More than a dozen staff and specialists have spent the past week in a frantic search for the marsupial, bringing in sniffer dogs and thermal drone technology to pinpoint her location.
A spokesperson for Paradise Country said the sightings were crucial to help the team in narrowing the search area, but that Mary had been "quite elusive".

The sighting has helped carers to triangulate a search area that backs onto the Saltwater Creek Reserve, with humane traps placed nearby in anticipation of Mary's movements.
Prime conditions for devil survival
Carers have found devil droppings in the surrounding bushlands, as well as the remnants of a kangaroo and wallaby carcasses.
University of Queensland captive animal expert Al Mucci said there were promising signs for Mary's survival.
"As long as there's food and water, she'll be able to survive comfortably for as long as she wants," he said.
"The weather is on her side, she doesn't have to adjust too much at the moment, the biggest threat is humans, dogs and vehicles."
He said devils could travel about 10 kilometres in a night, but not in a "straight line".
"[Mary is] moving quietly, she is nimble while cruising around the neighbourhoods and bushland," Mr Mucci said.
In a statement, a spokesperson for the Department of Primary Industries, which takes in Biosecurity Queensland, said it was working with Paradise Country to ensure the park met its obligations.
The park was closed after noticing Mary missing during daily morning checks to allow a widespread search, but reopened a day later.
