The Reproductive Health Care Reform Bill will be debated in the Upper House of the NSW Parliament today after passing the Lower House 59 votes to 31.

People have taken to social media overnight to express their outrage over the pre-recorded unsolicited message, where the federal member for New England urges recipients to oppose the bill, claiming it would allow abortions to be performed "for any reason up to the date of birth", including sex selection.

He has also reportedly urged recipients of the call to contact their state MPs and voice their displeasure with the bill.

The former Deputy Prime Minister has made his voice clear on the issue in recent weeks, launching an online petition and penning an opinion piece for the Sydney Morning Herald today with the headline "NSW abortion bill imposes death penalty on the innocent" labeling the bill an "incompetent legislation".

"It bases rights on the random timing of birth: after birth, you are a person; before birth you could face termination, which if it is on a day the baby could be viably born, basically reinstates the death penalty, though this time without needing a crime," Mr Joyce wrote.

"You have a responsibility to look after a baby after they are born.

"It is not a right that you can do as you wish with that person before they are born, as inconvenient at times as that may be."

It's not known how many people recieved the automated call overnight.
