Brisbane's lord mayor has put the cost of last week's flood damage in the city at more than $60 million.

However, Graham Quirk says council will have to pay about $23 million of the bill thanks to changes to the way national disaster funds are handed out.

Mr Quirk says he will be discussing the situation with federal minister assisting Queensland's flood recovery, Senator Joe Ludwig.

"To remove the restoration of damages to community groups and to parks, I think, is unfortunate ... I would hope that they would be restored," he told reporters.

"But as of December they were removed from the national disaster guidelines."

Mr Quirk said council would be able to get back only half of the $16 million needed for road repairs and none of the $13 million it will have to fork out to fix up parks.

As well, he listed $1 million for clean-up work and $845,000 for community group facilities.

Senator Ludwig says Mr Quirk is worrying unnecessarily.

"The existing rules are flexible enough to include things like parks and recreational facilities," he told the ABC.
