The free trade deal between Australia and Britain has been finalised and is expected to be formally announced by Trade Minister Dan Tehan and UK High Commissioner Vicki Treadell in Adelaide on Friday.
The in-principle deal between the two nations was unveiled in June this year following months of negotiations.
The initial text of the agreement included a request by Britain to enter a trade pact known as the CPTPP between 11 countries including Australia, Canada, Japan and New Zealand.
It also flagged cutting tariffs on whisky, clothes and cars as well as reduced levies on agricultural products.
There were five rounds of negotiations between delegates over the course of a year before the in-principle agreement was reached in June.
The UK is Australia's eighth largest two-way trading partner worth almost $27 billion in 2018.
It is also Australia's third largest services trading partner, with Australian service exports valued at $5.5 billion and imports totalling $9.2 billion in the same year.
