Normally you are limited to 30 free articles per month on The Age website, and it's partners eg SMH, WA Today.
However it appears when the same article is accessed through Canberra Times, there is no limit. Perhaps this is because public servants need to be most up to date with the news.
So when you hit your limit, replace the starting part of the URL to canberratimes.com.au
eg:
http://www.theage.com.au/technology/sci-tech/scientists-know…
To this:
http://www.canberratimes.com.au/technology/sci-tech/scientis…
Voila - no more limits!
nice trick
I always use "private tab" function to "bypass" smh limit
