Melbourne was rocked by an earthquake yesterday, with residents reporting strong shudders, offices being evacuated and tremors being felt as far away as Sydney, Canberra and Tasmania. 
Geoscience Australia initially said a magnitude 6.0 quake was recorded at 9.15am near the town of Mansfield, Victoria, but later downgraded its rating to magnitude 5.9. 
Newstalk ZB regular, Michael Rowland, was hosting ABC's News Breakfast when the quake struck.
