Not really the first section of the Constitution states, I added bolding; 
  
" 
  
 
An Act to constitute the Commonwealth of Australia 
     
[9th July 1900]     
WHEREAS the people of New South Wales, Victoria, South      
Australia, Queensland, and Tasmania, humbly relying on the      
  
blessing of Almighty God, have agreed to unite in one indissoluble      
Federal Commonwealth under the Crown of the United Kingdom      
of Great Britain and Ireland, and under the Constitution hereby      
established:"
 
 
  
  
  
If not specific then at the very least a very strong alignment with a "God" 
  
That I do not support hell and brim-fire type religious people, I do support the outcome of support outside of the current education system.
