(a) Risk of recidivism; evidence of change of lifestyle
19 The applicant's case before the Tribunal, as conveniently summarised in his written submissions on the appeal, was that there were factors which weighed heavily against deportation, despite the serious nature of the applicant's offences. They included:
"(a) the low risk of recidivism because of the Applicant's efforts at rehabilitation and significant changes in his lifestyle;
(b) he is in full‑time employment and is making a contribution (albeit late) to the Australian community;
(c) he migrated at the age of 12 as a refugee and so spent a considerable portion of his formative years in Australia;
(d) he has little remaining contact with Vietnam and does not wish to return there; and
(e) The evidence of the applicant, his fiancee and their family is that they would all suffer significant hardship if the applicant was deported."
20 Evidence of a change of lifestyle and attitude by the applicant was given, before the Tribunal, by the applicant himself, a consultant psychologist, Dr Hayes, the applicant's mother and brother and his fiancee's father. The Tribunal discounted evidence given by the applicant largely because of the applicant's own admission that he had told a number of lies in his evidence to the Tribunal. The Tribunal took the view that, in many respects, Dr Hayes' evidence was of little weight because the opinions expressed were based largely on information given to Dr Hayes by the applicant, who the Tribunal found was not to be believed. The applicant does not base any submission on the Tribunal's treatment of his own evidence or that of Dr Hayes to the extent that it depended on what she was told by the applicant.
21 The applicant's mother made a statutory declaration in which, among other things, she said this about the applicant:
"He is different to how he was before he went to prison. At that time, even though he lived with my husband and I, we saw less of him than we do now and we never spoke properly. He was thin and unhealthy. He did not listen to me and I thought he was a bad son. We had many arguments about his behaviour and the people he was with. Although at that time I did not [know] that he was using drugs, as I had no contact with them, I knew that something was not right. He was unhealthy and slept in. He was lazy and not interested in finding work.
Since he has been released from prison I have noticed a great change in Phuc. He is bigger and healthier. He watches what he eats and even eats fruit, which he never did. He is respectful towards his family and listens when I speak. He does not go out with his friends and he is happier. He has found a job and tells me that he is doing well. He was proud when the boss told him he was happy with his work and made him full‑time and gave him a rise in his wages. I have never seen him happy at work before now. I know that he gets up very early to go to work and that he never takes a day off. These are all things that he would not have done before prison and I see him as a different person."
22 The applicant's brother gave similar, though less detailed, oral evidence. His fiancee's father gave consistent evidence about the applicant's current attitude and lifestyle. So did his fiancee. The applicant's complaint is that the Tribunal did not address that evidence or, in dealing with the evidence of Dr Hayes, take account of the fact that that evidence supported the facts on which she based her opinion as to the likelihood of recidivism. Dr Hayes' views about the likelihood of recidivism were expressed as follows (following an assessment conducted on 8 February 1999):
"The likelihood of recidivism is low. Research on recidivism indicates that if the person remains drug free, has employment, lives in stable accommodation and has family support, re‑offending is unlikely. Mr Diep showed no signs of being drug‑affected during the assessment, and I have no evidence to disprove his statement that he is drug‑free. If he were to return to drug abuse, research indicates that this would be most likely to occur soon after his release from prison. The fact that he has remained drug‑free, to the best of my knowledge, for a considerable period of time is a very positive indicator. Another positive indicator of low probability of re‑offending is Mr Diep's lack of aggression. …
In considering the case of Mr Diep, I think it is relevant to note that he is of limited intelligence. He is, as noted above, functioning in the category of borderline intellectual disability, at a level lower than 92% of the population. Nevertheless, he achieved quite a lot during his term of imprisonment and since, including learning new and useful skills. His intellectual impairment no doubt had an effect upon the commission of the crimes, and his ability to be influenced by other people. He is a young man, with very little potential for aggression, who because of his intellectual disability could have been easily led by other, clever people. He also has difficulties with both the English language and the Vietnamese language, which may make it difficult for him to have understood what was going on during the commission of the offences. Mr Diep has now been out of gaol for 10 months, and has not re‑offended, which is a very positive sign as he [is] past the critical period for re‑offending. He did not re‑offend despite a lengthy period of unemployment."
