Australian police divers have arrived at the Kendall property where William Tyrrell was last seen as the search for the missing boy's remains enters its 10th day.

Police are inspecting two water tanks at the Benaroon Drive home where William, then 3, vanished in 2014.

Officers had already set up an approximately 50x50m search area about a kilometre from the house where they have been scouring the creek bed and surrounding bushland for evidence.

NSW Police returned to the property, belonging to William's foster grandmother, 10 days ago to launch a fresh search based on what they have said is new information in the case.

Police and other emergency services personnel have been clearing vegetation and digging up the ground around the creek.

Officers are combing through each bucket of dirt by hand under the guidance of forensic experts, including a hydrologist.

The creek had been drained but continual wet weather on the NSW coast meant it had partially refilled by Wednesday afternoon.
