In Australia, they don't even need to pay Property Tax (Land
Tax) for owner occupied property. 
In Singapore, despite the exorbitant HDB prices they charge you,
they still require that you pay a concessionary owner occupied
property tax.
The PAP government are greedy suckers, any money they see, they
want.
How else do you think they have such high reserves? It's all
taxed from her citizens.
What land is exempt?
Principal place of residence
Your principal place of residence is generally exempt from land
tax. You can usually only claim an exemption for a principal place
of residence on one property.
