Walker died in 1886 in
Concord, New South Wales, and was buried in the cemetery at
St John's Ashfield, He left a large fortune, and was survived by his daughter
Eadith. Under a codicil in Walker's will, he left £100,000 to establish the
Thomas Walker Convalescent Hospital in the Sydney suburb of
Concord West. The hospital was duly designed by Sir
John Sulman in the
Federation Free Classical style and built in 1893. In the early 1900s, author
Henry Lawson was several times a patient there, treated for his alcoholism. The Thomas Walker Hospital is now known as
Rivendell Child, Adolescent and Family Unit and specialises in the treatment of young people with problems.
Yaralla Estate still survives as the Dame Eadith Walker Hospital. Both hospitals are listed on the
Register of the National Estate. File:ThomasWalker8.JPG|Thomas Walker Convalescent Hospital File:YarallaMansion.JPG|Yaralla Mansion 2007 Image:Yaralla2.JPG|Yaralla 2009, now Dame
