The following link taking from the Department of
Foreign Affairs and Trade explains fully Australia's
aid in the Palestinian Territories.

It's worth a read:

The Australian and other Governments are blind when it comes to money not going where it is supposed too.

While slamming the US decision to cut aid to the Palestinians, the PA has purchased a private jet for Abbas.

By: Margot Dudkevitch, World Israel News

The Palestinian Authority (PA) announced it has purchased a $50 million private jet for its leader, Mahmoud Abbas. The move comes as Palestinians are asking Europe and other countries for financial assistance in the wake of the US decision to slash funds to the PA.

According to reports in the Palestinian media, the jet is due to arrive within a few weeks in Amman, Jordan.

Explaining the purchase, Palestinian officials said that $30 million came from the Palestinian National Fund, and the rest from the PA’s annual budget.

BS the money came from stupid Governments, the PLA do not give a stuff about the average person just themselves (the leaders).

How accountable is Israel with the money it receives
from the United States?

"Criticising Israel is not anti-Semitic and saying so is
vile. But singling out Israel for opprobrium and international
sanction - out of all proportion to any other party in
the Middle East - is anti-Semitic, and not saying so is
dishonest."

(Thomas Friedman. 2002).

Israel shouldn't get one cent from America, Israel is a nuclear nation who is not party to international nuclear treaties, it's actually stealing from US citizens.

But the US is complicated as Presidents rely on Zionist campaign contributions and also have Zionist controlled media and a powerful lobby.

I assume the money is given as part of UN obligations.
Don't care for the UN they are the ones more or less deciding our immigration quotas and stopping us from saying 'not our problem, go back to where you came from'.
