Today's threats from Tony Abbott to axe funding for Perth's rail projects, slash public service jobs, and rip billions in aid from the world's poorest people shows people must vote Greens in the Senate to maintain checks and balances.

"In the event of a Coalition Government it is crucial that one party doesn't get total control of Parliament, and Mr Abbott certainly reminded us of that today with his drastic cuts," said Greens Senator for Western Australia Scott Ludlam.

The Australian Greens have called on the Australian Government to spend a fraction of its multi-billion annual transport budget on building bike paths - an area of transport infrastructure ignored by both the older parties.

"The Greens' plan for an $80 million national annual funding program for cycling would come from unallocated funds in the Nation Building Two program, and will not affect funding for safety-related road projects," Australian Greens Infrastructure Spokesperson, Senator for WA Scott Ludlam said.

Years of underfunding and poor priorities have left Western Australia's transport system in bad shape. A great public transport network would make our state cleaner and healthier, would cut congestion - and would reduce the gap between rich and poor.

Perth Light Rail: we've secured $500 million for Perth light rail, which will transform the way our city works. Tony Abbott has promised to axe this funding, and only put money towards road projects - which won't give us the cleaner, cheaper city we need.

The Greens launched an $842 million plan today to deliver express bus services, a new for old replacement fleet of hybrid electric buses, and a new dedicated freight rail line in Western Australia.

Greens Senator for Western Australia Scott Ludlam said the initiative commits $300 million to providing express bus services and bus rapid transit to 15 hot spots in the metropolitan area, spanning some 60km - including Express Bus Services for Ellenbrook - linking into a North Eastern Bus Rapid Transit Corridor.

Greens Senator for Western Australia Scott Ludlam has moved to reveal details of Colin Barnett's rail plans today through a set of Federal Freedom of Information requests after the Premier blocked attempts to uncover relevant documents for the second time.

Greens Senator for Western Australia Scott Ludlam today described Tony Abbott's vow to axe Federal funding for rail projects, including $500 million for WA, as "deliberate public transport vandalism".

"After five years, Premier Colin Barnett finally got on board with the Greens Light Rail proposal. Then the Federal Government committed half a billion dollars. Now Tony Abbott is threatening the lot.

"Perth commuters are desperate for alternatives to traffic jams and rising petrol costs. We have solutions in sight, but not if Tony Abbott is Prime Minister.

Greens Senator for WA Scott Ludlam will visit Bunbury this Saturday 15 June to announce a costed Greens plan for fixing dangerous cycling routes and infrastructure in the Greater Bunbury area.

Senator Ludlam will also be launching a Bike Blackspot phone app and website, for Bunbury cyclists to identify further cycle routes needing improvement.

“The Greens are serious and passionate about giving people a safe option for riding their bike to work or school,” Senator Ludlam, a cycle-commuter himself, said.

An investigation exposing staff shortages and inadequate training in the State's rail system highlights the need to boost State funding and protect Federal funding from proposed cuts, the Greens said today.

Greens Senator for Western Australia Scott Ludlam said Tony Abbott has vowed to abolish Federal funding for urban rail if elected.

More than one year after warning Transport Minister Troy Buswell to fix a Perth cycling blackspot, a cyclist has been hospitalised after a crash at the very same site.

Greens Senator for Western Australia Scott Ludlam developed the bike blackspot smartphone app used to report the site to Minister Buswell.

"Cyclist Travis Deane told the Minister in writing that this cycling blind-spot needed mirrors on May 3rd last year. Today there are still no mirrors and he broke bones in a front-on collision with another cyclist," said Senator Ludlam.
