Market research and analysis Roy Morgan said in a statement that 2.9 million Melburnians used public transport during an average three months. This was the equivalent of 71% of residents.
Only Android users who use Google's payment platform, Google Pay, can download a myki onto their smartphones.
The company said nearly two-fifths of Melbourne’s public transport users (39%) used an Android phone while nearly half, 48%, used an Apple iPhone. The remaining 13% either could not say or used a lesser used phone such as a Windows phone.
In contrast, those of the pre-boomers generation, born before 1946, were the least likely to use Android phones with only 21% of Melbourne transport users doing so.
Roy Morgan chief executive Michelle Levine said: "Analysing Melbourne’s nearly three million public transport users who use the city’s buses, trains or trams in an average three months shows over 1.1 million (39%) use an Android phone as their main mobile phone.
She said the myki functionality was not yet available for the more than 1.4 million public transport users in Melbourne (48%) who used an iPhone although the Victorian Government had promised to provide this feature sometime in the future.
