Ashley Paul Griffith, 47, confessed to 307 offences committed at childcare centres in the Australian state of Queensland and overseas between 2003 and 2022. His victims were aged between one and seven.
Judge Paul Smith called the scale and nature of the crimes “depraved” and “horrendous”, saying “there was a significant breach of trust”.
In addition to this case, the BBC understands Griffith is separately accused of abusing more than two dozen children in the Australian state of New South Wales and Italy.
