I’m Sarah Durack, a science and mathematics teacher from Sydney, Australia. I founded Sponge to contribute positively to the teaching profession. I want to leave teaching in better shape than I found it back in 2009.

Sponge provides high-quality resources and support for educators. I hope my work will inspire others to pursue a teaching career and stay in the profession for many years to come.


Diary of a Teacher is a spoken diary of my experiences as a teacher. This podcast is recommended for teachers, tutors, and pre-service teachers.


Occasionally I’ll post videos of my lessons and tutoring sessions. Be a fly on the wall of my classroom!


Thinking about becoming a teacher? Tutoring is a great way to start honing your skills. Explore the range of tutoring courses to get a head start.
