Hi Chris,
I may have led you astray. I've misread the article in TROVE, and have the wrong number in Flinders St. Beak House is on the corner of Flinders St & Stokes St, and was rebuilt by the Beak Pastoral Co. in 1929 after a fire in the original building.
106 Flinders St. is on the Cnr. of Flinders St. & Wickham St. You can find more about it by going to this site;-
