The Victorian Government is starting a trial today to test the ability of automated cars to cope on busy Melbourne roads. The Government says the trial, involving already available technology from four different manufacturers, is the next step in preparing for a future of driverless cars. Motoring groups and the police are supporting the initiative, but say nationally consistent standards will be crucial to the success of driverless cars in Australia.

The Federal Government has been rocked by revelations Deputy Prime Minister Barnaby Joyce may not have been validly elected. Barnaby Joyce is the latest to be caught by uncertainty over his citizenship - telling Parliament he may be a dual citizen of New Zealand because his father was born there. Mr Joyce is staying on as Deputy PM while the High Court determines his eligibility, but the Opposition believes he should stand aside immediately. The case could have huge implications for the Coalition, which holds the Lower House with a slim one seat majority.

Allegations of treachery and collusion have dominated Question Time in Parliament, as the Government's citizenship crisis deepens. Deputy Prime Minister Barnaby Joyce revealed yesterday he was a dual New Zealand citizen, but is arguing he should retain his ministerial duties and vote, while the High Court makes a ruling. Mr Joyce's citizenship status emerged in the same week a New Zealand Labour MP asked about the issue, and the Government is now accusing the Opposition of trying to use a foreign parliament to bring down the Government.

A dumped Liberal party mayor has opened up on the faction bosses he believes are wrecking the Liberals. Steve Russell was Mayor of Hornsby Council in northern Sydney for four and a half years and was expecting to stay on as Mayor after elections next month. But he'd fallen out with powerbrokers in the party who engineered the recently announced decision to abandon merging smaller councils into bigger, more cost-efficient operations. It appears his successor, the former Federal MP Philip Ruddock, knew Mr Russell's fate before the party wielded the knife.

And the Government has announced the Melbourne local authority will be stripped of its power to hold any citizenship ceremonies as a result.
