Key points: A well dug by wombats has attracted a variety of native fauna to the unique water source.
The wombats have been compared to water diviners by one biologist because of how they dug right at the location of the underground water source.
He said the hole has been there for long time, but has recently grown larger as wombats dig deeper during the drought.
Mr Finnie said the "wombat soak" was often used by wombats, kangaroos, wallabies and wallaroos, but it was now vital to many more animals during the drought.
Mr Finnie, who is a retired Taronga Zoo veterinarian, said the animals had the hero wombats to thank.
"It's almost like the wombats are water diviners, they're finding the water and digging the holes to get to the water and the other animals are taking advantage of it," Dr Old said.
"We often call wombats ecological engineers because they're digging burrows and they make habitat for other animals. »
