In September, the ACT Assembly backed Greens crossbencher Caroline Le Couteur's push to make it lawful for doctors to prescribe drugs such as MS-2 Step.

Under existing laws, only registered medical practitioners can carry out the procedure in an approved medical clinic.

As a result, women in the ACT can only legally access a medical or surgical termination at Marie Stopes Clinic or, in limited circumstances, Canberra Hospital.

However, women could still source the pills via telehealth providers, which enable abortions to be carried out at home.

One doctor last year told The Canberra Times that she was aware of women travelling to Queanbeyan to access the drugs.

ACT Health officials told budget estimates hearings on Thursday that the new laws would come into effect on July 1.

General practitioners will first have to complete a training program before they are allowed to prescribe the drugs.

Ms Le Couteur welcomed news of the imminent arrival of the "well overdue" reforms. She described the passage of the laws as a "landmark moment" for Canberra women.

"Access to affordable sexual and reproductive healthcare, including medical abortion, is part of every person's right to control their own body - no matter where they live," Ms Le Couteur said.

"Canberrans will now no longer need to travel across the border to Queanbeyan to access medical abortion services.

Liberals health spokeswoman Vicki Dunne last year opposed the laws, saying the drugs were dangerous.
