Sorry if I took your posting the wrong way and thanks for putting me straight.
Mr Sheehan's articles have come under alot of fire and criticism for both their accuracy and content
To open an article about the Wallabies and then start talking about the Wallabies is typical of his diatribe which has put him under such scrutiny and probably explains his enforced "gardening leave" from the SMH.
Cheers.
