Australians mostly want to work for mining, energy and technology firms, according to a study released by professional networking site LinkedIn.

Mining giants Rio Tinto and Leighton Contractors are the most in-demand employers, with tech giant Google, construction company John Holland and Origin Energy rounding out the top five.

The list is based on data gathered from four million Australian users.  LinkedIn ranked firms according to how many users follow or view their pages or the pages of their employees.

The dominance of energy and mining companies reflects the Australian resources boom, LinkedIn said.  Globally, technology and consumer goods companies are king. Google is first followed by Apple, Unilever, Procter & Gamble, and Microsoft.

Rounding out the Australian top ten are Microsoft, placed sixth, followed by resources firm WorleyParsons, NBN Co, Qantas and Accenture.

WorleyParsons was the only Australia-based brand to make the global top 100 list, moving to 35th from 71st last year.

Globally, LinkedIn analysed 25 billion interactions between users and companies and surveyed thousands of users.

In the interest of fairness, it excluded itself from the analysis.

LinkedIn had 238 million global users as of June, up 37 per cent from the second quarter of 2012.
