The latest Roy Morgan Research into Australians' technology habits shows residents of the nation's capital are leading the way in home internet and mobile phone use to the detriment of the old rotary dial.

According to the research company, which surveyed more than 50,000 Australians, almost 80 per cent of households have internet access. In the ACT that number is just shy of 90 per cent.

Canberrans also have the highest uptake of broadband internet at 77 per cent while that national average sits at 68 per cent.

Roy Morgan chief executive Michele Levine was not surprised.

''What we are seeing is that the ACT has a more educated population, education levels are twice the national average, they are more affluent and more technologically proficient - so they can afford new technology and like to use it,'' Ms Levine said.

This had led to fewer households having a home telephone.

''In the ACT, mobile phones at 91 per cent, are now well ahead of fixed line, 78 per cent, and that represents a revolutionary move to person-to-person communication rather than the more traditional household-to-household communication,'' she said.

For polling companies that surveyed on home-phone lines this caused some problems.

''For companies that only do telephone surveys it is a problem … increasingly you have to get mobile phone numbers.''

The participants in this study were interviewed face to face. About 1200 were from the ACT.
