Brisbane lord mayor Adrian Schrinner has proposed expanding the Brisbane Metro project to Brisbane Airport, despite the first stage of the $944 million dollar project not yet having broken ground.

A parliamentary committee has recommended that a bill on a strengthened character test for visa applicants be passed in the Senate.

The measures would widen the grounds for visa cancellation and refusal; and make it easier to deport tens of thousands of migrants.

Under the proposed changes to Section 501 of the Migration Act 1958, visa-holders who have committed a crime that carries a maximum sentence of at least two years, such as common assault, will automatically fail the character test, even if they are not sentenced to jail.

The Chinese government’s claim states that it is "not permitted by international law" for other countries to make  "innocent passage" through the seas around this region.
