Hi Luke
Would you like to read the relevant page on this website for FHOG buying vacant land?
http://www.osr.nsw.gov.au/benefits/first_home/general/fhplus/
The way I read it, buyers pay no stamp duty if the purchase price is at or below $500,000. For properties above this amount, normal stamp duty imposts apply
Equally, the FHOG does not apply for purchases over the same threshold.
flipflops, all the technical information you have requested is available on the various government websites.
Stamp duties and other government fees and charges differ between the States.
The Commonwealth FHOG is $7,000 across Australia, but each State offers something extra for first home buyers.
However, there is a maximum value for the property being purchased. At $1.5million, you are beyond the scope of the FHOG.
But it all sounds wonderful and best wishes for a long and happy life in your own paradise!
Cheers
Kristine
