In Australia, both government and non-government schools operate co-educational and single-sex educational environments for students. The overwhelming number of schools are co-educational, with a small proportion of government schools operating single-sex schools, sometimes with a separate boys' and girls' school in the same suburb. All government single-sex schools are secondary schools. Examples of adjacent single-sex government secondary schools include Asquith Boys' and Asquith Girls', Canterbury Boys' and Canterbury Girls', North Sydney Boys' and North Sydney Girls', Randwick Boys' and Randwick Girls', and Sydney Boys' and Sydney Girls' (all in Sydney); and Melbourne High and Mac.Robertson Girls' (in Melbourne).
