Australia and Britain are heading towards a free trade deal during two days of talks in London.
This is despite British trade secretary Liz Truss having to apologise to her Australian counterpart as talks began.
Mr Tehan told Sky News: “I was very pleased that Liz rang and apologised when I landed in London with regards to that article.
“There’s tit-for-tat when it comes to trade diplomacy, obviously you’ll get people behind the scenes trying to push buttons here and there.”
The talks are the first face to negotiations between the two sides which have been virtual during the pandemic. The facetime seems to be accelerating progress.
Mr Tehan told Sky News they are going well.
“I am confident that we can get the deal done, it’s just a matter of sitting down and working through all the detail.
“They are quite complex and there are some sensitive issues, but the most important thing is that both countries come to the table in very good faith, wanting to improve the economic integration between our two nations.
“I’m absolutely confident that we can get a deal done.”
Mr Tehan, who worked as a barman in a pub outside Canterbury while a student in Kent University, said a deal would lead to a jobs bonanza for Australians and Britain.
He said: “If you look at our record and the free trade agreements that we’ve negotiated, in every instance they have enhanced and grown the economic relationship, they’ve enhanced and grown exports between the economies that we’ve entered into free trade agreements with.”
He added: “I’m a very firm believer it’s fantastic for the economy, and as importantly it’s fantastic for jobs, and that’s going to be really important as we come out of this pandemic.”
A deal with the Australia is an important part of the British government’s post-Brexit trade strategy.
It has negotiated deals with countries the UK already traded with as part of the EU.
Japan is the only country with which it has negotiated a deal differing from an existing EU deal.
And seeks the same with New Zealand, Australia and the US.
But the benefits should not be overstated. It’s estimated a trade deal with Australia could increase British GDP by as little as 0.002 percent.
