A New Tax System (Goods and Services Tax Transition) Act 1999

If you make a gambling supply before 1 July 2000 relating to a gambling event that happens on or after 1 July 2000, the gambling supply is instead taken to have been made on 1 July 2000 and is attributable to your first tax period after that day.

In applying section 126‑10 of the GST Act to work out your global GST amount, disregard:

all monetary prizes you are liable to pay at any time on the outcome of gambling events that happened before 1 July 2000; and

all amounts of money you are liable to pay, of a kind referred to in paragraph (b) of the definition of total monetary prizes in subsection 126‑10(1), to the extent that they relate to gambling events that happened before 1 July 2000.
