I've recently dealt with a matter where my client was the one that wasn't providing tax invoices for the supply of new residential premises (taxable supply, no margin scheme). In this case the contract was silent regarding issue of a tax invoice before payment. Interestingly, not one buyer out of more than 75 settlements requested a tax invoice.
Unless the purchaser was registered for GST, there is no expectation that a Tax Invoice would be issued for the purchase of residential property as residential property is input taxed ie the vendor would have been obliged to remit 1/11 of the sale price to the ATO.
