‘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.’

‘I used to be a high school teacher in maths and geography. 30 odd years ago I went to England and I was teaching over there for a long time – long enough to get married, have a daughter, get divorced. You know…the usual story. When I came back they’ve changed the rules on me. I’m no longer qualified. They consider me a new starter. I haven’t got a specialist teaching qualification so despite the fact that I’ve got 30 years’ experience including head of department I can’t teach without going back to uni for another year. I can’t afford that so I’m making scarves to keep myself above the streets rather than below them.’

‘If I sell a few scarves a week, I’m happy. The first couple of scarves buys all the wool I need. The next one buys me food for the week and the next one puts some petrol in my home.’
