Teacher Monica Elizabeth Young, 23, (pictured) is alleged to have sexually assaulted a young student on school grounds
A female teacher accused of sexually abusing a teenage student sent Snapchat messages asking the boy to send her explicit photos, a court has heard.
Monica Elizabeth Young, 23, was denied bail on Monday by a Bankstown Local Court magistrate, who raised concerns she could interfere with witnesses if released.
Ms Young was arrested and charged with 10 offences early on Friday morning including aggravated sexual assault with a child aged between 14 and 16.
Court documents revealed many of those charges related to incidents alleged to have occurred during school hours on June 24 and July 3.
Young was arrested at a Sydney home on July 10 and devices were seized.
Police had only briefly reviewed the recorded evidence but had already allegedly uncovered Snapchat conversations of the teacher 'encouraging the complainant to send an explicit image', the police prosecutor said.
'As a result, this is an overwhelming prosecution case,' she said.
Snapchat conversations and CCTV from the school showing the pair in contact formed part of the prosecution case, the court was told.
The boy also gave a recorded interview on July 3, leading Mr Walsh to suggest the teen's 'memory would not be a significant matter at trial'.

It is also alleged Young tried to interfere in the police investigation by contacting the pupil's mother to 'explain away' the claims.
Magistrate Glenn Walsh said that, according to the facts before him, Young learned about the existence of the police investigation then 'tried to get around' it.
The magistrate said Young allegedly did that 'firstly by representing herself as a different Snapchat user, and secondly attempting to contact the mother of the complainant to try and explain away the circumstances of conduct.'
The court was told that created unacceptable risk that Young could try and interfere with the administration of justice.
The teacher appeared in court via audio-visual link from Silverwater's remand centre dressed in a green prison jumper and her hair tied back in a ponytail.
The teacher appeared to quiver when she first appeared but calmed herself and was expressionless through the rest of her appearance.
Young's mother, grandmother and father all watched on as Young's barrister, Geoff Harrison, applied for bail on her behalf.
Mr Harrison told the court she could stay with her grandmother in Sydney's south-west under 'house arrest' conditions.
He said the teacher had spent 'some three days in custody' and said there was now 'strong incentive' for her to oblige and obey bail conditions.
She had no criminal record, could offer $50,000 surety and stay with her grandmother, he said.
But the magistrate said Young's alleged behaviour 'raises significantly bail concerns of interference of witnesses' and formally refused her liberty.
The teacher was just weeks away from marrying her boyfriend of six years when she was arrested last Friday at her home about 7am.
She was charged with ten offences - including multiple counts of aggravated sexual intercourse of a child aged between 14 and 16 over weeks.
The young woman is also charged with two counts of intentionally sexually touching a child, intentionally inciting a child to sexually touch and related offences.
A court on Saturday ordered that the names of any prosecution witnesses and the name of the school not be published.
And lawyers for Young sought a non-publication order on her name for a second time on Monday but it was refused by the magistrate after media opposition.
The case returns to court in August.
