EFAC Australia has just launched a website for Australian Anglican expository preachers.
https://www.expopreaching.org.au/.
This website is intended to be primarily a resource for preachers, especially beginners or those who are called to preach without a lot of prior training in theology or preaching. They can then see how other expository preachers deal with a particular passage or subject.
If you are a more experienced preacher, please register to add your sermons. The intention is to have full text sermons, not just audio or video files so preachers can follow the line of argument more carefully.
Many people use SermonCentral but are disappointed with the quality of much of what you'll find there, hopefully you find this website valuable as it continues to grow.
