A 38-year-old man allegedly at the centre of an incident with a baseball bat will remain in custody until at least April.
South-West Police allege that Harvey William George Nannup, of Glen Iris, drove to a residence in Denebola Crescent, Australind, around 7.20pm on February 2.
Mr Nannup allegedly assaulted a male occupant of the house with an aluminium baseball bat. The victim was asleep at the time.
South-West police said the victim received a fractured skull and swelling to the brain, and was flown to Royal Perth Hospital for treatment.
Police said the victim remained in a critical condition.
Bunbury Detectives appealed to the public for more information on the accused, as several members of the public may have seen Mr Nannup in the area of Denebola Cr, Millbridge Drive, and Eaton Dr between 7.30pm and 8.15pm.
The accused may have been seen wearing a Chicago Bulls T-shirt and carrying a baseball bat.
Mr Nannup appeared in the Bunbury Magistrates Court on February 3, before the charges were remanded to later that week.
He then returned to court on February 7 - via video link from Hakea Prison - charged with committing aggravated home burglary, stealing, and causing grievous bodily harm with intent.
Mr Nannup's defence told the court the accused would not be applying for bail at this time.
The lawyer called for the matters to be adjourned for "10 to 12 weeks".
Magistrate Belinda Coleman remanded all matters to April 23 for a committal mention hearing.
