An Australian man who cycled around Europe looking for his missing son has returned to Sydney with the six-year-old.
Ken Thompson, a former New South Wales deputy fire chief, retired from his job to cycle 6500km across Europe in a bid to find Andrew, who was taken overseas in April 2008.
The boy was taken out of Australia by his mother during a custody dispute, the ABC reports.
The father and son were reunited in Amsterdam in September last year and with the permission of Dutch authorities flew to Sydney last week.
Mr Thompson says they are glad to be home and is appealing to media to respect his son's privacy.
He has called on the Australian government to make it a crime to take a child out of the country without permission.
The boy's mother has been fighting moves to extradite her to Australia.
