@Ivy, you are correct:
@Kerry Lynch, you may try and pursue this via the criminal route. There is no statute of limitations for criminal prosecution. However, you will need to convince the police (or public prosecutor) to pursue your case against the perpetrator. Whether or not they do will largely depend on how much evidence is available. A criminal offence requires proof at a higher burden (beyond reasonable doubt) than civil (balance of probabilities), so you, and the police, may need more evidence for this route. Further, a criminal prosecution is on behalf of the state, which means the aim of the sentence is not compensating the victim (through there may compensation of some sort) but to a combination of retribution, prevention, rehabilitation and punishment. But it is a way to see "justice being done".
Have you tried seeking community support and speaking with others who have gone through a similar ordeal as you, to see how they dealt with their situation? The Queensland Government has a
support page (with links) for victims of abuse. It also may be worth contacting your
local community centre to talk about your options.
