THE Australian Christian Lobby (ACL) is urging federal parliamentarians to reject the latest attempt to legalise euthanasia.

The Australian Greens this week will introduce a private bill that seeks to overturn the Commonwealth's ban on the Northern Territory and the ACT legalising euthanasia.

The lobby says the minor party's strategy is legislation by fatigue.

State and federal parliaments have refused at least four attempts to legalise euthanasia in recent years.

"Parliamentary inquiry after parliamentary inquiry has found that euthanasia cannot be made safe for vulnerable people who might be pressured into prematurely ending their lives," ACL managing director Jim Wallace said in a statement on Monday.

"Nothing has changed to refute this evidence yet the Greens keep coming back."

Greens senator Richard Di Natale said his bill would overturn laws introduced by the Howard government.

He called on Labor and the coalition to allow their MPs a conscience vote.

"This is an issue where both major parties are seriously out of touch with mainstream Australia," he told reporters in Canberra.
