What is the cheapest flight option to earn 360 Qantas status credits from Melbourne?

Travelling a lot for work, but because I have just started, I am not going to make it to gold this tie around and do not want to wait til mid year next year to get it. With the current Qantas double status credits deal, can someone suggest the cheapest option to get 360 status credits?

There is an artice somewhere on the site (or was it in a newsletter), on the cheapest rates to get Gold.

Does anyone have the link?
