Pearl Marie Wilson, 60, was charged with murder in 2012 after her partner, Jason Shepstone, died in February that year.

An autopsy found Mr Shepstone had blunt force injuries over much of his body and burns to 20 per cent of his skin at the time of his death.

The autopsy also revealed the 46-year-old suffered from liver cirrhosis, the result of a long history of alcohol abuse.

In Port Kembla Local Court on Tuesday, Magistrate Mark Douglass ordered Wilson to appear before the Supreme Court in August for arraignment, after finding the Crown had a viable case against her.

"After considering all of the evidence, I'm of the belief that there is a reasonable prospect that a reasonable jury, properly instructed, would convict you of the charge you face," he said.

The cause of Mr Shepstone's death will be a key area covered during the trial, with defence lawyers suggesting that his death may have been caused by the effects of alcohol withdrawal, rather than the injuries on his body.

Multiple witnesses are expected to be called to give evidence, including investigating police, the forensic pathologist who carried out the post-mortem examination and specialist doctors who reviewed Mr Shepstone's case and were asked to give expert opinions on the cause and manner of death.

Magistrate Douglass continued Wilson's bail after prosecutors did not object to her being at liberty in the lead-up to the trial.
