SA welcomes fed move on GST carve-up

A federal move to legislate to ensure no states and territories are worse off under changes to the GST is a win for South Australia, the state government says.

Under a compromise agreed to by the coalition partyroom on Tuesday, draft laws will be introduced on Thursday containing safeguards to ensure every jurisdiction will be in a better financial position over a set period.

The guarantee will cover the transition period from 2021/22 to 2026/27.

South Australian Treasurer Rob Lucas says the state government made it clear it would not support changes to the carve-up of the GST that would leave SA worse off.

"This is a win for South Australia, and indeed the other states and territories, and will ensure we have funding certainty in the years to come," Mr Lucas said.
