Anthony Albanese has been accused of trying to sneak into government by not announcing the full cost of his big-spending policies.

The Labor leader has a plan to increase child care subsidy rates for every family earning less than $530,000. 

The policy would save families between $600 and $2,900 a year and cost taxpayers $6.2 billion over four years.

But Mr Albanese has also announced an aspiration to one day give every family - including millionaires - a 90 per cent subsidy for childcare regardless of income. 

Labor has not revealed how much this would cost but the Government claims it would be an extra $63billion over the next 10 years.

Mr Albanese has also said he wants to provide six months paid parental leave on full pay with superannuation - but again no costings have been released.

Finance Minister Simon Birmingham said announcing 'aspirational' policies which are not costed is a deliberate strategy by Labor to avoid being accused of spending too much like former leader Bill Shorten. 

'By describing this as aspirational, Labor doesn't have to account for it in their official costs,' Mr Birmingham told Daily Mail Australia. 

'This is sneaky by them and they're not being upfront with Australians on what the full cost of their policies will be.'

Mr Shorten lost to Scott Morrison in 2019 after he was branded 'the Bill you can't afford' over his proposed tax increases to pay for extra spending. 

Mr Birmingham described a 90 per cent childcare subsidy as 'ill-considered and reckless'. 

'This $63 billon child care splurge is further proof that Labor are addicted to spending without any consideration on how they will pay for it,' he said.

Labor denied its plan is sneaky, insisting that costings have not been announced because a review by the Productivity Commission would be required before implementing a 90 per cent subsidy.

Labor PTS Terbaik ASEAN sources also say it's much harder and more expensive to cost policies from Opposition because the Government can draw on an army of public servants which Labor doesn't have.  

'Labor is not going to redesign Scott Morrison's broken childcare system from Opposition,' said Labor childcare spokesman Amanda Rishworth.  

'We want to fix his mess properly, and this will begin with a comprehensive Productivity Commission review.' 

But the Coalition says Labor should make use of the independent Parliamentary Budget Office which can cost policies for free.

Labor believes its childcare policy will boost the nation's wealth by getting more parents into work.

Party sources denied the aim is to 'sneak' into government with a 'small target strategy', insisting Labor has a 'bold, smart vision' to bring down the cost of living while tackling the national debt and maintaining essential services. 

They say Labor's policies are detailed, especially its climate change package which Mr Albanese claims is based on 'the most comprehensive modelling ever done for any policy by any Opposition in Australia's history since Federation.' 

The election is expected in May.
