PREMIER Colin Barnett will take the plunge into cyber space on Tuesday by participating in his first live online forum via The Sunday Times' website PerthNow.

Mr Barnett will field questions from PerthNow readers for an hour from 2pm.

Mr Barnett said he was excited about his first online Q&A with voters.

"I am excited to be participating in my first live online forum and I encourage all PerthNow readers to send through their questions and I will do my best to answer as many as possible," he said.

PerthNow is WA's leading news and entertainment website. In June, PerthNow had more than 700,000 viewers.

There were more pages read by West Australians on PerthNow in the month than on any other WA website.

Meanwhile, the website received a staggering 60,000 story comments in June from readers keen to express their opinions on the stories of the day.
