Opposition leader Zed Seselja unveiled his shadow cabinet on Monday, on the eve of the first debates of the ACT's eighth Legislative Assembly.

The opposition will have a seven-person shadow cabinet with newcomers Giulia Jones and Andrew Wall handed junior portfolios of women and multicultural affairs, for Ms Jones and youth and indigenous affairs for Mr Wall.

Mr Seselja has taken an increased workload by taking over the shadow attorney-general's responsibilities from newly appointed Speaker Vicki Dunne and taking corrections and police from Jeremy Hanson.

Mr Hanson will retain health and take over community services, housing and disability.

The leader will also take responsibility for two new portfolios, cost of living and utilities. Deputy leader Brendan Smyth retains the shadow treasury role and takes on another new portfolio, economic diversification.

Alistair Coe will continue in territory and municipal services and takes on planning and infrastructure and the job of Opposition Whip.

Mr Seselja said Mrs Dunne was to take a ''traditional'' approach to the Speaker's job and would not have any portfolio work.

''That's obviously a loss for our party room. Vicki was a wonderful performer for us, but our party room's loss is the Parliament's gain and I think she'll be able to devote herself to the role of Speaker, which is very important to the Parliament and to the community.''
