Wentworth has a concentration of observant and non-observant Jewish people compared to other electorates. However, as Australian electors, voters in Wentworth who happen to be Jewish have a wide variety of interests and opinions including on the state of Israel and Australia's proper relationship with that state. Electorate, domestic or other international politics may be more important. Just as within the Jewish communities of Israel, a variety of opinions on the state of Israel exist within the Jewish communities in Wentworth.
The same can be said for the non-Jewish voters in Wentworth.
Here it is difficult to predict in that while Wentworth returns members for the urban conservative party in Australia, and that Australian conservatism has been associated even more so than labourism with supporting the existence and interests of the state of Israel, Wentworth traditionally preselects and returns much more "wet" (economically soft over hard right) and "liberal" (socially progressive, tolerant and pluralist) conservatives than other "safe" conservative electorates. Wetness and liberality in Australian politics is associated with multilateralism and human rights observance, issues which predispose politicians to be less supportive of some of the state of Israel's actions; and, which indicate an electorate with similar concerns.
Finally, contemporary ABC.net.au reporting indicates that at least one Jewish organisation in Wentworth does not appreciate being patronised by a government announcing major foreign policy changes apparently in favour of the state of Israel during a by-election in a seat with a concentration of Jewish communities.
It is difficult to plumb such an answer due to the variety of interests of all electors, the liberal pro-human rights returns demanded by a wet preselecting safely conservative electorate, and due to the variety of responses possible. It may well be that an increased liberality in the electorate's conservative voters counter balances the probability of a slight increase in pro-Israel interests amongst Jewish identifying labour and conservative voters. But it is certain to say that electors of any sort in Wentworth predominately determine their vote casting on issues other than policy surrounding Israel.
