Number 30 out of 178 is pretty good considering there is no such thing as a country without corruption and as the OECD is a very small group and 22 our of 33 is about middle. I would say in the overall scale of things Israel is not very corrupt. The With the corruption that does exist a large part of it is due to the system of coalition government. At the last election. There are currently MK's from 12 parties in the Knesset and at least twice that actually stood at the election but didn't win any seats. About 7 of those parties are in the coalition. When you have so many parties and you need them to form a government its all about pay offs and pay offs. Israel needs about 4 large parties rather than so many small ones giving small parties a disproportionate amount of power and coalition government should be replaced with directly elected constituency based government where the party that wins the most seats runs the country alone... no pay offs and what you see before the election is what you get after.
