Saint Patrick's Cathedral in Parramatta and St Francis Xavier's Cathedral in Adelaide held a solemn mass for the repose of the Pope's soul on Sunday morning.
Melbourne Archbishop Peter Comensoli will lead the celebration of a Solemn Pontifical Mass at St Patrick's Cathedral on Monday afternoon.
They are the first local services following the Pope's funeral at the Vatican on Saturday, attended by 250,000 people and watched online by hundreds of millions.
Maeve Heaney, director of the Xavier Centre of Theology at the Australian Catholic University, was among those who attended the service in Rome.
She said it was a coincidence that she was there for the funeral, after she originally travelled to Rome for a symposium on synodality.
Associate Professor Heaney, who had met Pope Francis on three occasions, paid her respects as he lay in state in the days before his funeral.
"There are people all over the world mourning because he was such a strong, beautiful figure … he had a prophetic presence to him, so there is a general sadness," she told AAP.
"The days before the funeral have been very intense but I have a feeling it will be more tranquil as we move into a period of mourning."
Following the mourning period, cardinals will gather in Rome for a conclave to elect the new Pope - a process expected to start in 10 days.
Prof Heaney hoped the new Pope would continue Francis's legacy of synodality.
"For me, it's also an important point about bringing more women into leadership positions," she said.
"I want to trust that (the voting cardinals) will sit down and think carefully about what the church needs today and choose someone who will continue to bring it forward."
