Labor leader Bill Shorten will be under increasing pressure to recognise Palestine after the party's NSW conference appears set to make an "historic" push to do so, despite some MPs complaining about "furious" lobbying by the Israeli embassy - something the diplomatic mission denies.

On Friday afternoon shortly before NSW Labor Right figures met to negotiate on the wording of a proposal that would "urge" a future federal Labor government to recognise a Palestinian state, state MPs received an email.

"Time and again throughout its history Israel has extended a hand of peace only to have it rejected by the Palestinians," the three-page document from the Public Affairs Section of the Israeli Embassy labelled as a fact sheet and obtained by Fairfax Media, reads. "The international community must speak up against the culture of oppression, genocidal rhetoric, terror and incitement that is prevalent among the Palestinians."

Former Premier Bob Carr told Fairfax Media there had been a "furious" lobbying campaign against the motion, which will "urge" a future federal Labor government to recognise Palestine and be voted on by 800 party conference delegates on Sunday.
