Who won the first men's singles title at the 1905 Australasian Championships?

Rodney Heath won the first men's singles title at the 1905 Australasian Championships. He defeated Albert Curtis in the final, 6–4, 6–3, 6–4.

The 1905 tournament was the first edition of the championship that eventually became the Australian Open. It was staged at the Warehouseman's Cricket Ground in Albert Reserve, Melbourne, and was played on grass. Heath's victory made him the event's inaugural men's singles champion and began a long record of Australian success in the tournament's early decades.

Heath returned to win the title again in 1910, defeating Horace Rice. Anthony Wilding won the championship in 1906 and 1909, while Norman Brookes became champion in 1911, so all three appeared in the early roll of champions but not in the 1905 final as winner. The tournament was called the Australasian Championships from 1905 through 1926, before changing its name to the Australian Championships in 1927.
