Opposition Leader Tony Abbott says the Coalition will seek to recognise Indigenous Australians in the constitution if elected to form a government this weekend.



Speaking at the Press Club in Canberra, the Liberal Party leader also vowed to make Indigenous policy the main focus of the Coalition government for one week out of 52.



The comments were made as Mr Abbott laid out his vision for how Australia would look at the end of a three-year term under the Coalition.

"If a Coalition government is elected, this is how Australia will have changed in three years' time," he said.

The budget would be "on track for a believable surplus" and economic growth "should be stronger", he added.

Because asylum seeker boats "would be stopped", there would be more room for people waiting in camps overseas to enter Australia, Mr Abbott added.

He also pledged to be an "infrastructure PM" who would oversee major upgrades to roads in five Australian states.

On the question of the Coalition's stance on Syria, Mr Abbott said any decision to send Australian troops to intervene in the Syrian conflict would be backed by a parliamentary vote.

"Ultimately, any decision to commit the armed forces to combat, any decision to put our service men and women into harm's way, should go before the parliament.



"Whether a parliamentary vote happens before or after combat commences, very much depends upon the circumstances. If for instance Australia was subject to imminent threat, it would be irresponsible of any PM not to act swiftly."
