This figure shows the age standardised notification rates of infectious syphilis, in New South Wales, the Northern Territory, Queensland, South Australia, Tasmania, Victoria, and Western Australia, between 2006 and 2011, by Indigenous status. The figure shows that across all years from 2006 to 2011, the age standardised notification rates were higher among the Indigenous population than the non-Indigenous population in most jurisdictions, except in New South Wales where notification rates were relatively similar between the populations, in Victoria where notification rates were higher in the non-Indigenous population in 2009, and in Tasmania notification rates were higher in the non-Indigenous population in 2011. In 2011, within the Indigenous populations, the figure shows that age standardised notification rates were highest in the Queensland, followed by South Australia, Western Australia, the Northern Territory, Victoria, Tasmania and then New South Wales. The figure also shows that the age standardised notification rates among the Indigenous population in the Northern Territory have declined significantly between 2006 and 2011.  In the Indigenous population between 2010 and 2011, age standardised notification rates decreased in New South Wales and the Northern Territory, and increased in Queensland, South Australia, Tasmania, Victoria and Western Australia. In the non-Indigenous population between 2010 and 2011, age standardised notification rates decreases in the Northern Territory and Tasmania, and increased in New South Wales, Queensland, South Australia, Victoria and Western Australia.
