But when he connects with patients suffering from mental illness and helps them on their road to recovery, it makes it all worthwhile.

"It has its challenges and those are different every day," he said. "Some days you make inroads, some you don't. But when you make those connections, and keep those connections, that's when you know you're doing a good job."

Mr Tattam's efforts were recognised this month when he received a Volunteer of the Year award at the Illawarra Shoalhaven Local Health District's annual public meeting.

He was humbled by the award, usually preferring to shun the spotlight. It's that unassuming nature that must appeal to patients going through tough times.

He doesn't make appointments - choosing to wander the wards to offer an impromptu counselling session to those in need.

"They just want someone who's real - who can talk to them about what they've been through," he said.

"It can get a bit heavy but it's about helping people through their grief and then empowering them to make the right decisions and seek the extra help they need."

After a tough period in his own life, he found his faith and since then has volunteered at community kitchens for the homeless as well as helping young offenders in prisons.

He said the work could be disheartening at times.

"It can be like a revolving door in these units - you see the same faces returning time and time again."

The festive season can be anything but for those in hospital, but Mr Tattam does what he can to buoy their spirits. Next week, he will conduct a Meaning of Christmas service.
