US President Donald Trump has sent an Australia Day message, declaring America has no better friend than Australia.

The message was delivered by acting Secretary of State Thomas Shannon Jr and comes just days after Mr Trump killed America's participation in the Trans-Pacific Partnership with Australia and other allies and as he considers whether to make it harder for Australians and Kiwis to travel to the US.

"On behalf of President Trump and the American people, it is my honour to congratulate the people of Australia as you celebrate this Australia Day, 229 years after the arrival of the First Fleet at Sydney Harbour," Mr Shannon Jr said in a statement.

"It has been over 75 years since your commonwealth and the United States established diplomatic relations, but connections between America and Australia reach back to that fleet."

The Los Angeles Times revealed on Wednesday that Mr Trump, in tightening up America's borders, is considering ending the visa waiver program that allows Australians, New Zealanders and citizens of 36 other nations, including many close allies in Europe, to easily visit the US on 90-day tourist visas.

A draft copy of Mr Trump's potential executive order on immigration and refugees flags the scrapping of the program and forcing visitors to the US to sit for in-person interviews with US officials before being approved for entry.

Mr Shannon Jr, however, talked up in Thursday's Australia Day message the ease with Australians and Americans can travel to each country.

"Today, travel is easier, and we are honoured to host almost 1.5 million Australians in the United States each year, with over 200,000 Australians here on any given day," he said.

"Half a million Americans are fortunate enough to visit your land each year.

Mr Shannon Jr also talked up trade, despite the TPP's demise that has left Australian Prime Minister Malcolm Turnbull and his government looking for a slimmed down TPP alternative or other trade deals.

"Today, Australia and the United States are top trade and investment partners, with $US65 billion ($A86 billion) in goods and services flowing between us each year," Shannon Jr said.

"The United States is responsible for over a quarter of all foreign direct investment in Australia and we are the top destination for Australian investment abroad.

"Our cooperation is deep and comprehensive: from space exploration to protecting the world's oceans to collaborating in the search for a cure for cancer.

"The United States has no better friend than Australia, and our longstanding alliance is a force for stability and prosperity in the Asia-Pacific region and around the globe.

"I wish all of your people a blessed Australia Day, and continued prosperity and peace in 2017."
