"This is the new face of terrorism, this is the new face of what we deal with," Deputy Police Commissioner Cath Burn said, as quoted by the publication.
The 22-year old suspect's attack, inspired by Daesh, was preplanned and Khan confronted police upon their arrival with the intention to attack the officers, according to Burn.
Khan will face the charges at Sydney's Central Court on Wednesday.
Last week, Australian Prime Minister Malcolm Turnbull warned of a "real" threat of terrorist attacks in the country after Daesh called on its supporters to carry out attacks against Australians.
On Monday, an Australian court sentenced to ten years of imprisonment a teenager from Melbourne suspected of plotting a terrorist attack on police.
Daesh, which occupies vast tracts of Iraq and Syria and is outlawed in many countries including Russia, has gained much notoriety for conducting suicide bombings and other attacks worldwide and recruiting young people via social media.
