Anna Bligh says plans to introduce fluoride to the water supply are her best achievement from her first year as Queensland Premier.

In the year since taking over from Peter Beattie, Ms Bligh has overseen changes to Freedom of Information laws, amendments to adoption laws and political donation rules.

But she says she is proudest of setting a timetable that will have 90 per cent of Queenslanders drinking fluoridated water by 2012.

“It’s been a very big year with lots of challenges and lots of learning for me. Without a doubt I think the thing I feel very satisfied that I’ve had a chance to bring is fluoride into Queensland’s water,” she said.

“I know it’s controversial out there, but I think it’s something that will leave a very long legacy of better dental health for our children.”
