Thousands of children across Australia would be made safer everyday if governments delivered on their promises for seatbelts on rural school buses, Australian Greens Deputy Leader, Christine Milne said today.

Senator Milne's announcement was made as numerous football teams show support for Victoria's ‘Buckle Up' campaign this weekend by wearing seatbelt sashes on their jumpers.

"Whether you are driving two minutes to the shops or driving all day, wearing a seatbelt is a major aspect of reducing our road toll.

The Australian Greens have called for a proposal for a National Student Card to be put on the COAG agenda as a matter of urgency, according to Greens Senator Sarah Hanson-Young.

Senator Hanson-Young, Greens spokesperson on Education, says it's important that the discrepancies between states and territories on tertiary student access to concession transport are ironed out as soon as possible.

"All tertiary students deserve access to concession transport, whether they be undergrads or postgrads, domestic or international students or TAFE students,'' Senator Hanson-Young said.

Australian Greens Deputy Leader, Christine Milne, and Greens Minister for Alternative Transport, Nick McKim joined forces today to commit to an improved and innovative public transport system for Tasmania.

"A Hobart Light Rail public transport system that links the state's capital with the northern suburbs will free up time and increase the attractiveness of Hobart to young people who realise that car commuting is a time waster.

"Texting, using a mobile phone and laptops are all common on work commutes and are possible on public transport. Research by experts such as Richard Florida show that it is the reason busy young people see it as a preferred choice providing flexibility and greater personal freedom and less expense.
