First Home Owner Grant

The First Home Owner Grant applies to newly built homes only, so it isn't available on an established purchase. A first home buyer building or buying new under $600,000 may qualify for $10,000 — see what qualifies with Revenue NSW.
At $1,005,000 this is $405,000 above the $600,000 First Home Owner Grant cap. A first home buyer may qualify for $10,000 on a newly built home — check eligibility with Revenue NSW.
