The search back at Kendall enters its sixth day today (Saturday, November 20). Rain could potentially hamper efforts into next week.
A hessian bag was the latest item exhumed from a search area off Cobb and Co Road, not far from the home formerly owned by William's late foster grandmother and from where he disappeared in 2014.
The item was found by investigative search teams near the site where a piece of blue cloth was found on Friday. Both items have been bagged as evidence and will be sent away for forensic testing.
Ground penetrating radar equipment was used on the concrete slab underneath the home earlier in the week while the gardens below the balcony were excavated and the soil sifted.
Cadaver dogs have also been used at the three locations of interest.
Water was drained from a nearby creek with the guidance of specialist hydrologist, Professor Jon Olley, who is working with and providing advice to police investigators.
Professor Olley was a part of the team who helped find murdered Queensland schoolboy Daniel Morcombe's remains in 2011.
