Mr Shorten is in Jerusalem today for the 100th anniversary of the Battle of Beersheba.

"I think that all of this current turmoil and chaos in the Australian Government and the Australian Parliament could have been avoided if Turnbull had simply stood Joyce aside until the High Court made its decision," Mr Shorten said.

"Turnbull is too arrogant for that, and because of his arrogance and his poor judgment we now have the current turmoil."

Mr Shorten said "more than 100 decisions" made by Mr Joyce should now be under scrutiny.

Mr Turnbull had been due in Israel on Saturday but revised plans after the High Court ruled on the citizenship issue affecting MPs and senators.

With the Prime Minister delayed, it was left to Veterans' Affair Ministers Dan Tehan to represent the Government in Jerusalem on Sunday.

"I think you will find that this will be an incredibly successful visit. Both when it comes to his meetings with the Israeli Government, but also when it comes to the relationship between Australia and Israel," Mr Tehan said.

Yesterday, Mr Tehan defended suggestions it was embarrassing for Mr Turnbull to delay his trip amid the citizenship fallout saying, "this sort of thing happens all the time".

Mr Turnbull's delay appeared to have little impact on his hosts in Israel.

"Israelis love Australians. And just in general I think Australia was always next to Israel," Israel's Deputy Foreign Minister Tzipi Hotovely said.

Australia is described by Israeli Prime Minister Benjamin Netanyahu as "one of the State of Israel's greatest friends".
