I would like to know about Australian Telephone Line.
What is the portion of Pulse Dialing Users vs Tone Dialing Users in Australia?
I heard Pulse Dialing is old-fashioned but would like to know the
rough percentage of the market. I need the answer by tomorrow. Thank you.

I am assuming you are talking about land lines, not mobile/cell phones.

Tone dialing is Australia wide.
A pulse dial phone will work to phone people, but not for message
bank, call waiting or any other features which rely on tone.
Your would probably need to look at the sales of pulse phones which
would be more a novelty/gift item than anything else.

This comment is probably too late to be of any use though.

Cheers
