Prime Minister Julia Gillard expressed Australia's sincerest gratitude to the Obama government for killing the most wanted terrorist.

"The death of Osama bin Laden is of course a great blow to terrorism. It's also a measure of justice for his victims and for a world he has changed forever," she said.

"As a nation we are simply relieved that his long career of destruction is over - a two-decade campaign that cost thousands of innocent lives,"
Gillard said.

If Australia was pleased, US, meanwhile, showed frustration upon finding out how Osama bin Laden communicated through email for years without being tracked.

Western authorities discovered that even without a phone line or internet connection bin Laden was able to send messages through email by saving them to a thumb drive and having them sent through a far-away internet café.

The primitive way of emailing entailed long hours. This leaves veteran intelligence authorities in awe of how bin Laden has endured the process for a long time.

Firstly, bin Laden would type his messages offline and save it in a thumb drive. He then passed it to a trusted messenger who would go to a distant internet café for emailing. The messenger would then save messages addressed to bin Laden to the same drive so bin Laden could read them offline.

The US Navy Seals who were part of Bin Laden’s killing confiscated more or less 100 flash memory drives at his Abbottabad compound in Pakistan.

Authorities told the Associated Press, the flash drives “appear to archive the back-and-forth communication between bin Laden and his associates around the world."

Moreover, the hoard of messages is so huge that the US government has recruited Arabic speakers from around the intelligence community to pore over them.
