Hillsong has a collective blog from all extensions that shares information about the ministry extensions it has across. Here's a description on it's blog website:
"Hillsong Collected is a blog. It is an ongoing collection of thoughts and stories from the leadership and key team of Hillsong Church around the world, conveniently packaged in three different streams.
We want to inspire and encourage everyday people that your efforts and contributions can and will make a difference. So take a look around, make yourself at home and check back often.
