We don't know what happened to Leanne. But no woman should be left like this.

On Sunday, a woman's body was discovered in bushland in Sydney's west.

She was lying next to clothes and rubbish at a reserve off Irwin Street in Werrington.

Detectives said she appeared to have been there for some time before a passerby discovered her.

Now, we know her name.

Leanne Akrap. She was 47.

Police set up two crime scenes, as forensic teams combed the area, which backs on to sporting fields and homes, on Monday and checked nearby bins for clues.

They also searched a unit about 500m away from where Leanne's body was found.

Speaking on Sunday, Detective Superintendent Trent King described the reserve as "quite isolated".

"It appears as though that body has been there for a period of time without discovery," King said.

Following inquiries, police arrested a 47-year-old man at a home on Powell Street in Hobartville, about 20km away from where Leanne's body was found, at about 6pm on Monday.

He was taken to Windsor Police Station where he was charged with murder.

The man was refused police bail and is expected to face court on Tuesday.

Police are yet to share the cause of death.

Leanne was the 34th Australian woman killed this year, according to Sherele Moody's Australian Femicide Watch.

A report will be prepared for the coroner.
