Pro-life advocates are pushing the Turnbull government to copy Donald Trump's ban on foreign aid money being spent on abortion.

The Australian Christian Lobby wants the Coalition to reinstate a similar ban, which was brought in by John Howard and later abolished by Kevin Rudd.

Wendy Francis, the lobby's spokesperson on women's issues, said it was a form of "colonialism" for Australia, through its foreign aid program, to impose a practice on women living in developing countries that were culturally opposed to abortion.

"In many countries, abortion is not seen as something women want," Ms Francis told Fairfax Media on Wednesday.
