About Knowledge Shop

Who we are

Knowledge Shop® has been helping accountants do what they need to do (and a bit more) since 2000. A subsidiary of ASX listed Easton Investments, Knowledge Shop® was born out of the frustration experienced by a profession trying to keep on top of an increasingly complex tax, super and regulatory environment. We help fill in those gaps.


We work closely with our former parent company Hayes Knight - an innovative accounting firm.


Culturally, we take our work seriously but not ourselves.  We let our knowledge speak for itself.
