Among the non-believers, increasing numbers are seeking spirituality elsewhere.
In the heart of Sydney's metropolis, there's a space for workers to stop and meditate.
For some it's a chance to de-stress during their busy day.
Others come looking for something more.
Centred Meditation Co-Founder Kevin Janks says while his meditation studio isn't affiliated with any religious or organised spiritual tradition, for some, there is a deep philosophical aspect to it.
Kevin's wife and Centered Meditation Co-Founder, Nikki says for her, the benefits of meditation go beyond the physiological.
"It's had such a profound impact on my life and gone so much beyond a stress reduction, but really helped me connect to what it means to be alive."
Based in the seaside town of Bondi [[bon-DIE]], Svenja [[sven-yuh]] Dahm has been practising yoga for twenty years.
Svenja says for her, and many of her students, their practice has a spiritual element.
"I think people find different things they are connected to, but I think the most import thing is to connect to yourself. And the moment you find that, I think that is a form of spirituality and people are definitely finding that and looking for that.”
In the 2016 census, a third of Australians described themselves as having no religion.
Within that group, an increasing number are seeking spirituality elsewhere.
University of Sydney Professor in religion Carole Cusack says people have many reasons for turning away from organised religion.
"It's become increasingly clear, at least in the last two decades, that most religious organisations are corrupt financially or they have covered up crimes, or injuries towards the most vulnerable in the community, children, the elderly, the intellectually disabled, anybody who's been placed in their care. And this is something that causes people to be very, very cautious and rather cynical about wanting to belong to such an organisation."
When asked whether those seeking spirituality outside of religion were grasping for something else to believe in, Professor Cusack was adamant that's not the case.
She suggests instead that people are adapting to a society where many aspects are becoming increasingly complicated and uncertain.
