Hugh Jackman's actress wife Deborra-lee Furness' campaign to overhaul adoption laws in her native Australia will expose some children to a greater risk of abuse and trafficking, according to experts.

The Jindabyne star has been a vocal supporter of the Adopt Change organisation, and this week (beg25Aug14) she praised the country's Prime Minister Tony Abbott for holding talks with campaign staff.

However, a group of child protection experts has now warned politicians that a change in the adoption laws could leave the door wide open to abusers.

The panel told an Australian parliamentary committee the proposals will make the adoption process "vulnerable to reduced standards for the protection of children, and greater risks of malpractice".
