Foreign Minister Penny Wong has refused to confirm if Israeli President Isaac Herzog will visit Parliament House in Canberra during his four-day state visit.
Under questioning from Greens senator Barbara Pocock, Wong said Herzog would not address parliament, but a question about whether he would visit would have to be taken on notice.
"There's obviously [a] heightened security environment," she said.
"If I take some of these questions on notice, I would just ask you to understand that that is the reason for it."
Asked if it was appropriate that Herzog's visit was funded by taxpayers, given allegations of war crimes levelled at Israel over its actions in Gaza, Wong said: "He's coming here to honour, remember the victims of that attack and support the Australian Jewish community."

A United Nations Independent International Commission of Inquiry (COI), which does not speak on behalf of the UN as a whole and has been sharply criticised by Israel, concluded in September that Israel is committing genocide in Gaza.
The commission also said Herzog, Netanyahu and former defence minister Yoav Gallant had "incited the commission of genocide" in their speeches and statements.
Israel is separately defending a genocide case at the International Court of Justice (ICJ), which has ordered provisional measures but has yet to issue a final ruling.
Israel has repeatedly denied committing genocide in Gaza, saying it has the right to defend itself. Herzog has vehemently denied allegations that his remarks amount to incitement, saying they were taken out of context.
Wong also could not confirm how much the trip was costing taxpayers.
Independent senator David Pocock asked Wong if she would raise the issue of the dozens of graves of Australian soldiers in Gaza reportedly being bulldozed by Israeli forces during military operations.
"As a matter of principle, the graves of fallen Australians are sacred to us. We would always make clear the priority we attach to the resting place of Australians," she said, taking the remainder of the question on notice.
Pocock then read out an email from the daughter of an Australian World War Two soldier buried in the cemetery.
"My family is distressed and angry, as we were led to believe by the War Graves Commission that very few Australian people's graves have been affected," Pocock read from the letter.
"I'm also distressed that the Australian government has very lately invited the president of Israel to Australia when our soldiers' graves have been desecrated by the Israeli Defence Force."
Wong said the issue was a matter for the Department of Veterans' Affairs.
