Alexander Walker, who might be called the ‘Founder of Mungindi’, died suddenly in 1878. His wife and family continued to run the Post Office, store and hotel. Apparently Mrs Walker became well known as the 'Queen of Mungindi'. Stories say that it was common to see over 100 horses tied up outside the hotel. If a ‘blue' started she would let down the slip rails and take to the horses with a broom. By the time the horses were rounded up the reason for the fight would have been forgotten and everyone was happy again. Presumably Mrs. Walker was no longer compelled to keep law and order in this unique way after the first NSW constable was stationed in 1882.
