Excerpt:
An Australian Islamic State supporter who called for an anti-Islamic event in Texas to be attacked has now posted a link online to a guidebook that explains how to join the extremist group.
The 50-page e-book, called "Hijrah (Journey) to the Islamic State", was tweeted overnight by a user known as Australi Witness who has 410 Twitter followers.
It was previously posted to Islamic State supporters via social media on March 14 this year.
