There has been an overall increasing trend in multiple births in the last two decades in Australia. Attributed largely to the increased use of fertility drugs and assisted reproduction technology and the growing number of older mothers.


In 2015, according to the Australian Bureau of Statistics (latest report as of December 2017) there were the following multiple births in Australia:

  • 4,291 sets of twins, representing 1.4% of all births
  • 84 sets of triplets and higher order multiples, representing 0.03% of all births
