Indonesia has expressed concern over the rising popularity of Pauline Hanson's One Nation party in Australia, ahead of President Joko Widodo's visit this weekend.

Asked about the increasing popularity of One Nation and its anti-Islam platform, Indonesia's top Foreign Ministry spokesman Arrmanatha Nasir said radicalism was a concern for both countries.

"I think it's a concern for any country," Mr Nasir said.

"It's a concern for Indonesia when it happens in Indonesia. I'm sure it's a concern for Australia when it happens in Australia.

"It's important for both Indonesia and Australia to intensify people-to-people contact so they get a better understanding of what Islam is all about.

"There is cooperation done and continuing to be done to share our culture, Islamic culture, because as you can see in Indonesia, Islam can go perfectly hand-in-hand with the modern world, with democracy, with other religions.

"These are the values and cultures we like to share with our Australian colleagues."

Mr Widodo will arrive in Australia on Saturday for talks with Prime Minister Malcolm Turnbull.

A planned trip by Mr Widodo to Australia last year was cancelled because of riots and religious tension in Jakarta.
