News.com.au reports that spokesman Hugh Ryan said that that any Catholic supporting the termination of a pregnancy disqualified themselves from receiving communion.
"Catholic doctors don't perform abortions," Mr Ryan told News.
"Anyone who kills is excluded from communion."
Earlier, Pope Benedict had said commented that politicians supporting the legalisation of abortion would be liable to excommunication.
"It is what is foreseen by the church's doctrine," the Pope was quoted as saying.
"(Life) is always a gift, even when lived in the most difficult circumstances."
Mr Ryan told News that no true Catholic would ever support abortion.
Mr Ryan conceded it was possible for an excommunicated doctor to physically receive communion at another church in anonymity.
"But that would be sacrilege."
The Pope's comments would do nothing to discourage Catholics from entering medicine, he said.
"(The church's stance on abortion) has never stopped Catholics becoming doctors from the start."
"There's even a Catholic doctors association."
