"Whichever way you look at it, whether it's the construction

sector or whether indeed its public transport, there are

increased costs," he said.

But David Bradbury, the parliamentary secretary to

Treasurer Wayne Swan, said federal Treasury modelling 

showed only a 0.5 per cent increase in public transport 

fares from a carbon tax.

"Mr O'Farrell used dodgy figures to try and justify (claims

of) a budget black hole when he came into power," he told 

Macquarie Radio on Friday.

"He's now using dodgy figures to try and justify unjustifiable

price increases by state public transport authorities."
Mr O'Farrell shot back, saying his figures were solid

analysis performed by his department and Transport NSW.
"The problem with federal Labor's calculation is they are

Australian-wide averages," he said.

"If Labor was fair dinkum about supporting public transport,

the carbon tax wouldn't apply to public transport."

Luke Foley, opposition climate change spokesman, labelled

the government's figures as "very, very rubbery".
"Mr O'Farrell must stop his despicable scare campaign about carbon pricing," he told reporters.
He also threatened to involve the Australian Competition and Consumer Commission (ACCC).
"If Mr O'Farrell tries to increase public transport fares by the amount he's citing today and blame the carbon tax, I will personally refer him to the ACCC for price gouging."
