When questioned about how much of the 99c for each text vote the charity gets, a Mediaworks spokesperson said they did not retain any of the money.
"Net proceeds from the text-to-vote mechanism go to the contestants' nominated charities. MediaWorks does not retain any money from the text votes however we can't speak on behalf of the telecommunication companies which deduct service provider charges from the cost of voting.
"Given this is for charity, we feel strongly that as much of the proceeds as possible should go to the wonderful causes supported by the show."
The country's three biggest telcos, Vodafone, Spark and 2 Degrees, have all been approached for comment.
A 2 Degrees spokeswoman said they couldn't comment about how much of the 99c was taken by the company as it was "commercially sensitive" information.
However, she addled service provider, Connexus, also took a cut for its services.
A Spark spokeswoman said they also couldn't provide a breakdown but said its cut was a "minority proportion".
She said it's rate was its "standard wholesale rate for a premium text" service.
Each week, the Dancing With The Stars contestants start with a clean slate, meaning votes and judges scores from the previous week no longer matter.
