The Federal Opposition has capitalised on its final days in control of the Senate, by blocking a raft of the Government's budget measures.
It could be seen as the last hoorah of the Howard years, with the Coalition using its majority in the Senate to refer several budget measures to committees for further scrutiny.
The controversial fuelwatch scheme, and a boost to the medicare levy surcharge are two of the measures bounced back.
The luxury car tax will also be reviewed, which earned a thumbs up from the automotive industry.
Andrew McKellar from the Federal Chamber of Automotive Industries says drivers were never consulted about the plan.
"There was chance for motorists to really put their case to how this tax increase would affect them."
But, Labor Senate Leader Chris Evans says the committees process will cost more than $280 million and has accused the opposition of Economic vandalism.
"That's what occured today: wilful, wanton and malicious destruction of the government's budget."
However, the Coalition says the goverment is rushing through legislation, and the delay is needed for appropriate senate scrutiny.
