australian radio hams can be traced to the early 1900s. the 1905 "wireless telegraphy act" while acknowledging the existence of wireless telegraphy, brought all broadcasting matters in australia under the control of the federal government. in 1906, the first official morse code transmission in australia was conducted by the marconi company between queenscliff, victoria and devonport, tasmania. however, it must be noted that some sources claim that there were transmissions in australia as early as 1897 – these were either conducted solely by professor william henry bragg of adelaide university or by prof. bragg in conjunction with g.w. selby of melbourne.
