A recent poll commissioned by Fairfax Media revealed that almost 70 per cent of NSW voters support changing the law to allow voluntary euthanasia for terminally ill people.

If the bill is passed through the NSW senate and referred to the lower house, MPs from major parties will also be granted a conscience vote but both Premier Gladys Berejiklian and Opposition Leader Luke Foley have said they are personally opposed to the plan.

But Mr Grant said he has conducted his own polling within the electorate, and will be guided by those results when he votes.

“I think community response is important and I will be guided by that, which is why I’ve been running my own poll,” he said.

“At the moment 58 per cent of people that have responded are in favour of voluntary euthanasia, so unless something drastic happens between now and November 14 when I expect the bill to come up then that is the way I will vote.”

The NSW bill was devised by a cross-party working group of MLCs and requires patients be over 25, likely to die of their illness within 12 months, and have approval of two medical practitioners. 

Medical practitioners can choose to opt out of any treatment for ethical reasons. 

Aside from those polled who supported the notion, about 18 per cent of voters are undecided, and 13 per cent were opposed or strongly opposed. 

More than 87 per cent of Nationals voters supported the question and about 61 per cent of Liberal voters and 73 per cent of Labor voters.

“My poll is lower than the Nationals vote and other areas, but each electorate has different beliefs,” Mr Grant said.

“I am comfortable in my own mind that it doesn’t mean more people will die, it means less people will suffer.”
