Bill Shorten has signalled an intention to make high-tempo campaigning a permanent feature of this term of opposition, beefing up his office with the appointment of the respected political strategist, Andrew Thomas, as his new chief of staff.

The 45-year-old Mr Thomas is an experienced political adviser, having served in previous Labor governments including a stint as chief of staff to the then treasurer, Wayne Swan.

He replaces Cameron Milner, who only joined his staff in September last year but indicated he wanted to depart after the election.
