‘My mum passed away when I was about 19 so I had to look after my brother and sister on my own. They were 12 and 13 at the time. I don’t know how I did it. It’s hard looking after teenagers at any age. I managed for about 4 years and then I couldn’t do it anymore so my sister went to live with my family up in the country and my brother went to my dad.’

What do you miss most about your mum?

‘The fact that I didn’t have to be responsible. I miss her all the time. Every day.’

‘The saddest moment in my life was when I went to Long Bay Jail. I spent 2½ years in there. I robbed a 7-Eleven in Matraville. I was an alcoholic and a drug addict.’

What did it teach you?

‘Gratitude. Loss of freedom. It taught me to be humble. It taught me to respect others – that you can’t take other people’s money or belongings. I’ve turned all that around in my life. I now go down to Mathew Talbot every Tuesday and feed the homeless. I give back; try and make up. I haven’t been back to prison since 1999. I intend not to go back. I’ve got 3 businesses and I went to acting school.

‘It’s hard when you’re in prison because you’re judged by the police first and you’re judged by the judge and jury. Then you’re judged by Corrective Services and then you get out of prison and you’re judged by society.’

What was the hardest thing when you came out of jail?

‘Getting accepted again by society – them not knowing that I’d changed. There are some people in society that want help; that want rehabilitation. I’ve learned my greatest lessons from my biggest mistakes.’

‘I last saw my brother at Manchester airport 20 years ago when I was 7 years old. He was leaving for Australia. I clearly remember giving him a hug and saying goodbye and that we’d see each other again.

‘We communicated by hand written letters over the years. All his letters were always so loving and positive. Whenever he used to phone at Xmas and would say goodbye to me, he could barely talk he was so upset. I really remember not understanding why he was so sad. I think it became easier over the years not to make that call and just to cut himself off a bit.

‘He didn’t phone at Xmas in 2003 and we got a bit worried. He’d been travelling around Australia and promised he’d be better at keeping in touch. He was always at this one address at Stanmore so we always knew we could get hold of him there.

‘Shortly after that, I got the last letter I’ve ever had from him. It was really sweet. He said never to worry about him and he’s very happy. I carried on writing after that but we didn’t hear anything for a while.

‘In 2009, I got every single letter I sent him to Stanmore sent back to me unopened, altogether in a big package.

‘I came out last year for 2 months to look for him. I’ve contacted the Salvation Army, Missing Persons Register, Red Cross. I went to the electoral roll and visited every Martin Roberts in Sydney. I wrote to every single Martin Roberts across Australia. I’ve checked the death register. Nothing. Immigration says he hasn’t moved on so I know he’s here.

‘I’ve given up my life, my job, my partner, everything to come out here again to look for him. Police have confirmed there is a Martin David Roberts with his date of birth listed to an address in Newtown. That’s the best news ever because it means he’s still alive because there is a part of you that starts thinking something awful happened to him.

‘He was seen 4 months ago at Newtown station and around 9 months ago at Town Hall station and apparently he’s a bit of a regular in pokie rooms around Newtown.

‘I don’t want to judge him for anything he’s been through. I don’t need a justification or a reason. None of us do. I just want to tell him that I love him and that he’s loved and missed.’
