Jump down to:


Sex Offender Register

Upon conviction of sexual offence charges, not only is imprisonment a likely outcome, but it often results in the convicted person being placed on the sex offender register under the Community Protection (Offender Reporting) Act 2004.

That then leads to the convicted person being subject to a continuing obligation to report to authorities, prohibitions or limitations on their travel, and in some cases, their property being confiscated under the criminal confiscation laws. It then becomes difficult for them to find employment and their life is never really the same again.


Allegations of Committing a Sexual Offence

Sexual offence allegations can be complex. Where the allegations are historical in nature it can make the charges more difficult to defend.

There is no time limit for the police to commence a prosecution for serious sexual offences. The police can bring a charge even when the sexual offences are alleged to have occurred decades ago.

False accusations can be made for different reasons. This often becomes apparent within the courtroom following rigorous and thorough cross-examination of the complainant.

Sexual offence allegations carry a stigma that frequently leads members of a jury to abandon their duty of objectivity and to set aside their emotions. This is an important consideration in the defence forensic strategy and the manner in which prosecution witnesses are cross-examined.

Andrew Williams understands the law as it relates to sex offences. He has a depth of experience in both Magistrate contested hearings and District Court jury trials. Andrew Williams will not judge your circumstances, but will fight to get you the best outcome, whether that be a judgment of acquittal or no term of imprisonment is served.


Frequently Asked Questions

Unlawful indecent assault is an unwanted touching or threat to touch someone else’s body in a sexual manner without that person’s consent. 

For an assault to be indecent the act that constitutes the assault must be sexually motivated. 

Sexual coercion is where a person is manipulated, tricked, pressured or compelled by another to engage in sexual behaviour.

Sexual abuse involves sexual behaviour or sexual acts toward another person without that person’s consent at law. 

Sexual abuse often refers to sexual behaviour or acts by an adult toward a child because the law recognises that children are not capable of giving informed consent to any sexual act or behaviour.  

Some do sexual offences charges do and some don’t. A person charged with a sexual offence can either plead guilty or not guilty to the charge. 

A plea of not guilty will always result in a trial hearing which can be heard in either the Magistrates or the District Court depending on the nature of the alleged sexual offending. 

Where a person enters a plea of guilty, the matter will proceed straight to a sentencing hearing. 


The prosecution must prove that the accused person committed the alleged offence. The prosecution must also prove its case to the required standard of beyond a reasonable doubt. This is the highest standard of proof known to our law. 

It is not enough for the prosecution to simply “tips the scales” and prove that the accused “probably” committed the offence. Every elements of the charge must be proved by the prosecution beyond a reasonable doubt. The accused is not required to prove anything. 

The elements of the sexual offence charge that the prosecution will be required to prove beyond a reasonable doubt will depend on the particular charge that is before the court.


Generally sexual offence charges do not trigger mandatory sentencing. Judges have a broad discretion when imposing sentences. The judge’s sentencing discretion is guided by the maximum penalty for the offence and whether the protection of the community requires the imposition of a custodial sentence.  

However, where an adult commits a serious sexual offence in the course of conduct that constitutes an aggravated home burglary, the mandatory sentencing laws may apply and the court sentencing the offender may be required to impose a term of imprisonment of at least 75% of the maximum penalty for the sexual offence. 

For example, the offence of aggravated sexual penetration without consent carries a maximum penalty of 20 years imprisonment. If this is committed during an aggravated home burglary, the court would have to impose a sentence of at least 15 years imprisonment.


Sex offences include but are not limited to:

  • sexual penetration without consent,
  • indecent assault,
  • indecent dealings with a minor,
  • incest,
  • lewd acts in public,
  • prostitution,
  • persistent sexual conduct with a child
  • using electronic communication to procure a child to engage in sexual activity
  • sexual offences against a child of or over 16 where in a position of authority
  • loitering and solicitation,
  • possession or distribution and of child exploitation material.

Sexual offences are serious matters and carry tough penalties in Western Australia. It’s therfore advised that you contact a criminal defence lawyer for advice and court representation, to ensure your rights are protected and that your future safeguarded.

The issue of consent arises in many sexual assault cases. “Consent” means consent freely and voluntarily given. Consent is not freely and voluntarily given if it is obtained by force, threat, intimidation, deceit or any fraudulent means.

A failure of a person to offer physical resistance does not of itself constitute consent. A person cannot have been taken to consent where that person is asleep or unconscious or where that person is so affected by alcohol or another drug as to be incapable of consenting. Nor can a person be taken to have consented in a situation where the person is mistaken about the identity of the other person involved.

Upon conviction of a sex charge not only is imprisonment likely as well as the conviction being recorded against the offender’ name, but in many cases, the offender is placed on the sex offender register. This situation will result in a continuing obligation upon the offender to report to authorities, be subject to prohibitions on travel, and in some cases property confiscation. These matters in themselves can lead to difficulty with maintaining your career or finding future employment.

Testimonials Hear from our valued Clients

Words cannot express my gratitude for Andrew agreeing to take my case on, commit to returning from annual leave early, and the personal support and legal expertise provided in defending the driving charges made against me.

The delays I experienced by the two adjournments, while prolonging my anxiety and reducing my faith that I would receive a favourable outcome, worked very much in my favour but moreover it was the multiple submissions and arguments that Andrew made at law on my behalf that cemented the somewhat miraculous outcome including two spent convictions.

Though I genuinely never for a second doubted Andrew's skills, experience and abilities, my fate felt somewhat pre-determined given the significant impact sustained by the complainant.

Andrew was kind, non judgmental, clearly experienced and committed and he accommodated my anxieties and emotion surrounding the charges laid against me.

Andrew went out of his way to give me the best chance possible for a favourable outcome that, in the end, the Magistrate considered and responded accordingly.

All in all, I could not have dreamt of a better outcome considering the circumstances and I...

I had Andrew deal with my case recently and couldn't of been happier with the result he got for me. From the start Andrew was quick to reply to any questions and queries I had regarding my matter. He was very professional in my opinion, very easy to talk to and explained things quite well. I felt very comfortable in the courtroom knowing that Andrew wanted to get the best result he could for me, and I would highly recommend Andrew Williams to anyone who needs a criminal lawyer.


Colin W

I was on a very tight rope where, if it balanced the wrong way, it would have totally devastated my life. Andrew was honest through the entire process preparing me for the worst but never let me give up and thankfully with his help got a great outcome that let me move forward with my family. I cant praise Andrew enough and recommend him 100%.

Had Andrew defend a reckless driving charge. He gave good solid advice throughout the process and defended me well at the trial. His costs were affordable and he was a great guy in general. The most important thing is we were able to have the charges dismissed via a not guilty verdict. I would recommend him to anyone.

Andrew represented me recently in a few difficult situations. I found him to be very professional, easily contactable and generally wanting a good outcome for me. I've passed his contact info to friends and if I ever need legal representation again I'll definitely be using his services.

After making several calls to various law firms, I came across Andrew Williams who was quick to respond providing knowledgeable, honest and friendly legal advice. At all times I felt confident in Andrew's ability to defend the charges. The case went to trial with an outcome of not guilty. I was awarded full legal costs. Could not be happier.

Of my limited experiences in the judicial system, I can’t rate Andrew Williams highly enough. He was fantastic on my day in court and was very straight up during my consultations. He is such an awesome person, and the best professional criminal lawyer I have ever encounter. Need help call Andrew.

Kyley S

Andrew was very approachable, knowledgeable, professional and focused on the best outcome. I would always recommend him.


Kieran C

My personal experience with Andrew Williams was a pleasant one from day one. In the midst of a police raid and the inability to find legal representation I considered myself done for when Andrew took the time to call me back after I contacted his office (during which time he was in trial). Upon soliciting some legal advice, Andrew was straight with me and I made an appointment with him in which he clearly explained the seriousness of my case. After some time, when the matter was moved to the District Courts I was well aware that I would likely be looking at some jail time; the nature of the legal systems and the way in which bureaucracy works is an extremely draining and mentally exhausting process. However, Andrew kept me well informed at every step of the way and promptly wrote to prosecution at critical points outlining my circumstances.

Moving forward, on the sentence hearing day, a pivotal point of my life occured when I was given no immediate imprisonement and was offered an opportunity before the Judge, being legally represented by Andrew. At no one point did I feel like I was being fooled or not taken care of, Andrew Williams was honest and professional, however harsh and difficult it was to accept my circumstances at times. In ...

Franciosco R

I was charged with the offence of aggravated common assault. I engaged Andrew Williams to act for me.

From the first time I met Andrew I knew that I was in the right hands. His level of professionalism both in and out of the court room was very impressive. Following a two day trial in the Perth Magistrates Court, I was found not guilty.

Andrew Williams assisted me through a very stressful period and I was extremely happy with the outcome. I would certainly recommend Andrew Williams to anybody that found themselves on the wrong side of the law.


Kyran H

My wife and I were so glad that we chose Andrew Williams to handle our sons Reckless Driving charge. What a relief to know we have people like him around to help.

Besides a failure to indicate and cutting the corner of a very sharp S bend in the road all other allegations by Police were not substantiated. After using a previous Law firm that basically told us that it was the 2 Police Officers word against our son and that we were probably better to take the charge of Dangerous Driving that had been offered by Police for a plea of guilty. $2500 later we decided to find someone else that at least believed our sons version of events.

Well, Andrew was that person; he understood exactly what was going on. He advised us of all avenues available to us and recommended the assistance of a very professional crash expert who provided quality photographs and measurements of the area involved.

Well if not for the professional and well thought out approach that Andrew used in this instance our son would have been unfairly charged with reckless driving for a very minor traffic offence. All costs were awarded to us by the Court and all I can say is...

George M

I have nothing but good things to say about Andrew and his law services. He helped me more than I could possibly ask for during a difficult time facing the court. He was very efficient and precise and always happy to help and answer questions even last minute and after hours.

I believe he charges a very fair price considering the amount of work he put in for me to achieve the best possible result in court and keeping me updated regularly through the whole process.

Without a doubt I will be recommending Andrew to all of my friends for future reference.


Trent W

I trusted that Andrew was the person to defend my case in our initial contact on the phone. He was very confident in his approach, from the first point of contact to the court room. I believe this must be from years of experience. Another added bonus for Andrew is that he is very honest and fair. He tells you like it is in the book of law and does not appear manipulative. His communication skills helped me help him to form a best defensive argument for my case. In other words, he made me comfortable to open up to him. In the end, he was able to convince the judge to let me off with only warning for providing misleading information to the police officer, which can be recorded as a criminal record against your name for 10 years.


Abraham A

Unhappy with my then representation, I went searching for a new criminal lawyer. Andrew responded quickly and professionally to my enquiry. It was quickly apparent during the first meeting that Andrew was knowledgeable, honest and was committed to getting us the best possible outcome. Andrew looked at all avenues available to me in a Magistrates Court matter. He negotiated on my behalf with the prosecution, attended 3 court hearings and defended my plea at a sentencing hearing. Andrew presented strong arguments in my defense and I was very pleased with a successful outcome. Andrew was also transparent and reasonable with his capped fee costing structure.


Timothy R

After being charged with Common Assault of a minor I made a sensible decision not to use the local Kununurra law firm. I engaged Andrew Williams to assist me with resolving this matter (to the point of me being awarded costs). Despite being 4000km away I never had any issues with Andrew's commitment to my case. He promptly returned all calls and demanded I do likewise when important information needed to be exchanged. I found him to be an intelligent, straight-talking and knowledgeable legal counsel. I have no hesitation in recommending this likeable and professional lawyer to those that require legal representation. Especially those that reside in regional or remote areas where there is no choice.


David C

Andrew Williams is a criminal laywer of much dedication I will never have the words of gratitude and admiration for his honesty and integrity I would highly recommend him to anyone who may require his services in the future


Helen M

I just wanted to take my time to explain my experience with Andrew Williams. I had an incident that could have really affected my future. As anyone does I called around all the lawyers in Perth and just not any lawyer but the ones who are highly respected amongst other lawyers and get the results. I have a friend who works in the industry and she recommended Andrew. She said she always sees Andrew in the paper with amazing outcomes to cases that he gets for his clients I first called his office and left a message with the receptionist. At the time he was on leave and it was his wife birthday. He promised her he wouldn't be bothered with work (this was at christmas time as well) he made the effort and called me to see if I was okay and how everything was. From that moment on I knew I had found my criminal lawyer. When you are going to court you want someone who is going to care about you and go the extra mile and not just pay you off. From the whole experience he was straight with me and very honest. My case was not an easy one and it could have been a very bad outcome. Andrew went out of his way to get me what I wanted. Throughout the whole process I felt like I was dealing with a friend. He was very professional and got the outcome I wanted. I really couldn't ...

Not only is he a great guy I found his legal services very professional and knowledgeable and his attention to detail was faultless. This was a very tumultuous time in my life I was facing two criminal charges and my anxiety and stress levels were through the roof, but thanks to Andrew's cool calm and confident demeanor he was able to walk me through it and keep me focused every step of the way. I was acquitted in both cases thanks to Andrew. I would like to take this opportunity to thank you again Andrew you did a fantastic job.
