Deandra Kontou

Introduction

Deandra Kontou is a former geography teacher at Newington College, one of Sydney’s most prestigious private schools, who has been charged with nine child abuse offences over the alleged grooming and sexual assault of a male student who was under 16 at the time. Kontou, 32, taught at the school between 2017 and 2019 under her maiden name, Haralambidis, and was arrested in Sutherland in late September 2026 after police reopened an investigation into the allegations. She was granted conditional bail and is scheduled to appear in Burwood Local Court in late November. The charges have not been tested at trial, and everything described here comes from court records and police statements as reported in the press.

Background Information

Newington College is a K-12 school centred on its Stanmore campus in Sydney’s inner west, founded in 1863, with fees above $48,000 per year and around 2,000 students across its Stanmore and Lindfield campuses; it began admitting girls in 2026 after a contentious decision that reached the courts. Kontou joined the school as a geography teacher while a newlywed, according to the Daily Mail, which reported she was praised in a personal trainer’s social-media posts around that time for keeping up gym sessions despite “a busy work life as a school teacher and after-hours tutor”. She left Newington in 2019 — the year the allegations were reported to school administrators, according to the New York Post — and later taught at Georges River College Senior Campus in Oatley, a public high school, until her arrest.

The Controversy or Incident That Led to Their Cancellation

Charged, not tried. Kontou has been charged but has not entered a plea, and no court has tried the charges. The account below comes from court documents and prosecutors’ statements described in news coverage; nearly every act attributed to her is framed in those sources as alleged. She is presumed innocent unless and until a court rules otherwise.

According to court records reported by nine.com.au, Kontou was charged with aggravated sexual assault of a victim under authority of the offender — an offence equivalent to rape under NSW law — three counts of aggravated sexual touching, and using a carriage service to groom a person under 16 for sex with someone else, among the nine charges. The Sydney Morning Herald listed the charges as including inciting a person to partake in an aggravated sexual act, four counts of sexually touching another person, and inciting another person to sexually touch her and have sex with her. Detectives believe the alleged victim was under 16 at the time of the attack, the Herald reported, and the investigation by the Inner West Police Area Command restarted in 2025 after allegations against her had been conveyed to police in previous years.

Prosecutors allege the conduct spanned roughly six months in 2017: that Kontou showed indecent material to the student and messaged him before coercing him into sexual acts, and that the incidents took place in the school’s Stanmore building during school hours, the New York Post reported, citing court records. She is also accused of touching the student twice during a senior boys’ trip to Fitzroy Island, some 1,200 miles from Sydney, and then sexually assaulting him.

Public Reaction and Consequences

Newington College confirmed Kontou’s former employment and said it “does not tolerate conduct by individual teachers that is in conflict with our professional standards or the law”, adding that it could not comment further while the matter was before the courts. Acting deputy head Mark Morrison told The Greek Herald the school’s thoughts were “first and foremost” with the alleged victim-survivor and their family. The case drew attention in Australia and abroad partly because of the school’s prestige — the Post noted its fees and its roster of prominent alumni — and partly because Kontou is the second teacher connected to Newington to face alleged sex-offence charges in recent months: in May 2026, part-time music teacher Benjamin David Collinge was charged with allegedly grooming a 14-year-old girl online, though police said no Newington student was involved in that case.

The documented consequences have been substantial: Kontou was arrested and charged, granted conditional bail only under strict conditions, and her teaching accreditation has been revoked by the NSW Department of Education, according to The Greek Herald. She remains employed by the department on “alternative duties” and, per the Herald, on its payroll, though the charges do not relate to her work at Georges River College and she is not accused of wrongdoing there.

Current Status

As of early October 2026, Kontou is on conditional bail awaiting a return to Burwood Local Court — the Herald reported a date of November 25, nine.com.au November 26. Her bail conditions require her to surrender her passport and not attend any international point of departure, report to Sutherland Police Station daily, stay away from school grounds and any teaching work involving contact with children, avoid contact with the alleged victim and prosecution witnesses, and not be in the company of a child without another adult present, according to the two outlets. She has not publicly commented on the charges, and the available coverage records no plea and no named defence attorney.

Impact on Their Career/Life

A nine-count child abuse case has ended Kontou’s classroom career in all but name: revoked accreditation bars her from teaching in NSW, her bail conditions bar her from schools and child contact, and her name is now attached in coverage to allegations of raping and grooming a student at one of Australia’s best-known schools. The case has also drawn scrutiny to Newington’s recent history — two teachers charged with child sex offences within months — and to the department’s decision to keep an accused teacher on alternative duties and payroll while the prosecution proceeds. If convicted, she faces the sentencing range of NSW’s child assault statutes; until then, every allegation remains untested in court.
