Family First upper house MLC Sarah Game has not ruled out introducing another bill restricting late-term abortion access.

Ms Game's proposed legislation to restrict abortions after 25 weeks failed in the lower house on Wednesday night.

Premier Peter Malinauskas was in support of the bill, but says he is not interested in a group of people obsessed with the issue "hijacking" parliament.

Family First upper house MLC Sarah Game has not ruled out introducing another bill restricting late-term abortion access, after her proposed legislation to restrict abortions after 25 weeks failed in the lower house last night.

Ms Game's bill passed the upper house yesterday afternoon 10 votes to 9 with the support of three newly-elected One Nation MPs, but was voted down in the lower house 36 votes to 9, following less than two hours of debate.

"I'm not ruling anything out at the moment, but I'm going to have to have a really good look and probably a really good speak to people who voted against the bill and understand, whether there's actually any movement there on further conversation," Ms Game told 891 ABC Adelaide.

Ms Game's bill would have effectively banned abortion from 25 weeks onwards except when necessary to save the life of the mother or in cases of serious fetal abnormalities.

The original bill precluded fetal abnormalities as a reason for access to a late-term abortion, however the exemption was later included after an amendment by Labor MP Tung Ngo.

Ms Game says it is "telling" both the premier and leader of the opposition supported her bill. (ABC News: Che Chorley)

South Australian law permits abortions after 23 weeks, with the approval of two doctors, if the continuation of the pregnancy would involve "significant risk of injury to the physical or mental health" of the pregnant person.

She had previously argued that the bill would "protect vulnerable human life", but those who voted against the bill said it contradicted the advice of medical professionals.

Premier Peter Malinauskas and opposition leader Ashton Hurn both voted in favour of the bill, but neither spoke in parliament.
