Background
9 The following summary of the factual background is largely taken from the decision of the Tribunal, based on the evidence given by the applicant before the Tribunal. As explained below, while the Tribunal recited the evidence given by the applicant, it did not make factual findings in respect of much of that evidence. Accordingly, the following summary records evidence given by the applicant, not facts found by the Tribunal. Where relevant, the following summary also refers to remarks made by Hampel J of the County Court of Victoria when sentencing the applicant for certain offences on 15 July 2016, and some reference is also made to three prior statements of the applicant: the first in May 2008 which was submitted to the Department in connection with a Partner visa application; the second in a Statutory Declaration made on 16 October 2017 for the purposes of the revocation decision; and the third in a written statement prepared for the Tribunal hearing.
10 The applicant was born in Thailand in 1977. She grew up in the city of Sukothai, Thailand, a city around 4 hours' drive from Bangkok. She has one younger brother, who lives in Thailand with her parents. At the hearing before the Tribunal, the applicant gave evidence that she had a difficult upbringing and had a troubled relationship with her mother, who the applicant said could be violent at times. In the County Court of Victoria criminal proceedings, evidence was given to the effect that the applicant had told a psychologist, Gina Cidoni, that she had enjoyed a happy, normal childhood in relatively comfortable circumstances.
11 At the age of about 15 or 16, the applicant moved to Bangkok, where she met and began a relationship with Mr BW. She lived with BW for one year before they separated, after which the applicant learned that she was pregnant. In 1998, she gave birth to her son, NK. The applicant's son was raised by the applicant's grandparents in Sukothai. The applicant gave evidence that her parents were sentenced to 13 years and 8 months in prison for drug-related offences in 1999. In 2004, BW died. During this period, the applicant worked in Bangkok in an office and completed a Diploma of Accounting.
12 As noted above, the applicant first came to Australia for a holiday in 2006. The applicant next came to Australia in 2007 on a student visa, aged about 30. She worked in a restaurant and a factory in Sydney, and also worked in what she described as a massage shop and that this work sometimes included the provision of sexual services. The applicant met Mr CO during her employment at the massage shop and they subsequently married on 4 March 2008. CO is a Turkish-born Australian citizen whom the applicant described as "controlling, abusive and violent". She gave evidence that CO forced her to engage in sex work.
13 On a date that is not clear from the applicant's evidence, the applicant and CO returned to Thailand and lived with the applicant's parents in Sukothai. CO then moved to Bangkok and took up with a new girlfriend. In the Statutory Declaration sworn on 16 October 2017, the applicant stated that she separated from CO when he moved to Thailand in 2012. It is difficult to piece together this aspect of the chronology.
14 The applicant gave evidence before the Tribunal that she first started taking drugs in 2012 due to her long working hours. She also gave evidence that she had been diagnosed in Australia with a brain tumour in 2013. She then began regularly using drugs in 2013, which the applicant claimed she did to cope with the stress caused by her brain tumour diagnosis and the sexual assault she endured as part of her work. She started using methylamphetamine (ice) and cocaine, but denied using heroin. The applicant was prescribed a course of medication for the tumour for 1 year and has subsequently been advised that the tumour is benign.
15 In late 2013, the applicant met Mr HN as a client and they commenced a relationship. They moved in together to an apartment in Southbank, Melbourne, which was leased in the applicant's name. In 2014, the applicant brought her son, NK, to Australia because her grandparents were no longer able to care for him. At about that time, the applicant and HN moved to a property in Truganina, Victoria.
16 On 24 September 2014, Victoria Police executed a warrant on the Southbank apartment and seized a large number of cannabis plants. On 30 September 2014, during the course of a police interview, the applicant admitted that she was aware of HN's hydroponic equipment located at the Southbank apartment. The applicant was not charged with any offences at the time.
17 The applicant gave evidence that, on 1 September 2015, police stopped the vehicle in which she was travelling with a companion and discovered a number of items which included: a cigarette containing cannabis; a bag containing 1 gram of the drug ice; and, in the applicant's handbag, a further 3 bags of the drug ice. The applicant was arrested and charged with trafficking in the drug ice, possessing a controlled weapon (a meat cleaver) and dealing in property suspected of being the proceeds of crime. She was released on bail and directed to appear at the Heidelberg Magistrates' Court on 30 November 2015.
18 On 30 September 2015, Victoria Police executed a warrant on the Truganina residence. The applicant, HN and NK were present. When the police arrived, the applicant was wearing a gardening glove with blackened tips and was carrying gardening shears. Police discovered that two bedrooms of the property were set up as "grow rooms" and that there were 69 cannabis plants at various stages of maturity, weighing approximately 31 kilograms. Police also found various other items at the house including 476.6 grams of dried cannabis, 12 ecstasy tablets, 6.7 grams of the drug ice, an amount of cash, two handguns and a taser. The applicant, HN and NK were arrested. NK was later released without charge.
19 On 15 July 2016, the applicant was convicted by the County Court of Victoria of the following offences: cultivating a commercial quantity of cannabis; possession of a drug of dependence (6.7 grams of the drug ice and 4 grams of ecstasy) (two charges); possession of an unregistered general category handgun (a .38 Colt); and three summary charges including possession of ammunition, a prohibited weapon (a taser) and dealing with $710 suspected of being the proceeds of crime. HN was convicted of cultivating cannabis.
20 In her reasons for sentencing, Hampel J noted that:
(a) When arrested, the applicant denied having any involvement in the cultivation of the cannabis, claiming that the plants belonged to HN. Plea discussions began, but the matter did not resolve at that stage and ultimately a contested committal hearing was scheduled for both defendants. By the time of the committal hearing, admissions were made by both defendants resulting in the convictions.
(b) The applicant had no previous convictions. However, she was facing charges arising out of the events on 1 September 2015, recorded above.
(c) HN had received a community corrections order arising out of the discovery of the cannabis crop in the Southbank apartment, referred to above. HN had also been convicted of trafficking in heroin in 2007.
(d) At the sentencing hearing, the applicant no longer asserted that the cannabis crop belonged to HN. Through her counsel and a psychologist who filed a report, Ms Gina Cidoni, the applicant stated that she was cultivating the cannabis crop in order to support her ice habit. She also claimed that the ice and ecstasy, although of traffickable quantities, were for her own use. Her counsel stated that the applicant had instructed that she was keeping the gun for another person.
(e) The applicant stated that both she and HN were ice users. Their relationship had become violent and they had broken up for some months, before resuming the relationship some months before their arrest.
(f) Submissions were made on behalf of HN to the effect that: the cannabis crop belonged to the applicant; he did not stand to gain any benefit from it; and his involvement was limited to allowing the applicant to continue cultivating the crop in his house after he became aware of it.
21 Judge Hampel expressed concerns about accepting unsupported assertions as to the respective roles of the applicant and HN in respect of the cultivation of the crop. Having heard submissions made on behalf of both defendants, her Honour stated that there was an air of artificiality or unreality about what was put on behalf of both defendants about their involvement and their respective roles. Her Honour stated that she had doubts that the crop was solely the applicant's and that she was solely in possession of the firearm, ammunition and taser having regard to the ownership of the house by HN, the manner in which the house was set up to grow the crop and the presence of both defendants when the search warrant was executed. Her Honour expressed a sense of unease that the applicant was taking sole responsibility for what was, at the very least, a shared venture. Judge Hampel asked counsel for the applicant whether his client's pleas were entered in the exercise of free choice and were fully informed. Counsel responded by stating that the charges before the court were the result of negotiations conducted over a number of months, where the ground shifted a number of times and which were ultimately resolved. He said that the applicant was represented at all times but, as far as he knew, the applicant was fully informed, aware of the case against her and her options. Counsel said that he was unaware of any pressure being brought to bear on the applicant by anyone. Judge Hampel accepted what counsel said and, despite her Honour's concerns about the position of the applicant, proceeded to sentence her on the basis that she had been independently represented, well and fully advised and must be taken to have entered her pleas in the exercise of a free and informed choice. Her Honour made the following observations (at [60]-[64]):
[60] According to what you told the psychologist, Gina Cidoni, who assessed you for the purposes of the plea, you have had, in Thailand, before you came to Australia, what you described as a happy, normal childhood in relatively comfortable circumstances. You reported being shocked to discover that your parents were charged with and subsequently imprisoned for 14 years for drug trafficking when you were aged 20.
[61] You told Ms Cidoni that you came here on a student visa, but despite that, seemed to have worked for much of your time here as a sex worker. You married after your arrival in Australia, but told her that it was an unhappy and abusive relationship and that you were forced to remain in sex work, not only to send money home to your family in Thailand, but to also to (sic) assuage the demands of your estranged husband, who was threatening to imperil your resident status. Apparently a divorce is pending but not finalised.
[62] You reported that you met [HN], who was initially a customer at the brothel where you were working, and that the two of you formed a relationship which was marred and marked by the mutual use of methamphetamine. You reported being subjected to violence and paranoid and jealous behaviour. The relationship broke up, then resumed in the months leading up to your arrest. According to you, it is now over.
[63] Based on what you told Ms Cidoni, you came to drug use only recently and your use of ice escalated when you met Mr Nguyen. She reported the relationship as tumultuous and she considered your judgement was seriously impaired when you began offending. According to Ms Cidoni, you present as naïve, gullible and easily led. Although Ms Cidoni notes that ice use is associated with increased autonomic activity, perceptual disturbances such as delusions, hallucinations and bizarre mentation and behaviour and psychological changes, such as agitation and affective blunting and impaired judgement, as they are the result of your ice use, they are not mitigating factors.
[64] Ms Cidoni's assessments of you were limited by poor language, despite the assistance of an interpreter. On the limited testing that she was able to do, she concluded that there was evidence of emotional disturbance with chronic depression, anxiety and interpersonal sensitivity, signs of thought disorder and paranoid ideation, possibly linked with your history of abuse of methamphetamine and other substances. She considered your cognitive function to be at borderline level. It is difficult to work out from her report whether that was due to language difficulties or your depression, anxiety and acute distress at the time of the conducting of the assessment. There did not seem to be, on my reading of her report, a finding of impaired intellectual capacity. Ms Cidoni did note that your acute distress related to the circumstances you now found yourself in.
22 In considering the applicant's prospects of rehabilitation, her Honour concluded (at [69]):
I consider the consequences already visited on you already (sic) count as significant personal deterrents and that your prospects for rehabilitation should be regarded as good. So far as the other offences are concerned, I consider it is likely that you possessed the other drugs, as you instructed, for your own use and that you were able to buy them in greater than single use quantities, by reason of your cultivation activities.
23 Judge Hampel sentenced the applicant to 3 years and 3 months, with a non-parole period of 1 year and 6 months. The applicant sought leave to appeal her sentence on the grounds that it was manifestly excessive and that the sentencing judge had erred in imposing the maximum penalty on summary charge 13 (commission of an indictable offence whilst on bail) notwithstanding the applicant's guilty plea. The Court of Appeal allowed the appeal and resentenced the applicant to 2 years and 9 months' imprisonment, with a non-parole period of 1 year and 3 months.
24 On 23 December 2016, the applicant also appeared before the Heidelberg Magistrates Court and was convicted of several offences (arising from the 1 September 2015 charges): possession of a traffickable quantity of the drug ice; possession of a controlled weapon without excuse; and dealing with property suspected of being the proceeds of crime. The sentence for these convictions was fixed at an aggregate 42 days' imprisonment, which was to be served concurrently with the sentence given in the County Court proceeding.
25 In the applicant's statutory declaration dated 16 October 2017, the applicant stated that she pleaded guilty to the "Truganina" charges because HN told her that, if she admitted guilt, he and his family would take care of her son while she was in prison. She also stated that she was told by her lawyer that if she pleaded guilty she would not go to jail for long and would be back with her son in less than 1 year. In her written statement prepared for the Tribunal hearing, the applicant repeated the statements that HN's family came to see her in prison and told her that if she admitted the charges they would look after her son.
