Greens MP Jamie Parker has urged the Government to act to build the GreenWay alongside the light rail project in a passionate speech to the NSW Parliament on the petition of 10,000 signatures in support of the project.

"Today is just another step in our campaign: the collection of 10,000 signatures is a great achievement and it is evidence of the groundswell of community support for the GreenWay," Mr Parker said.

"It was this same campaign, this pressure, which forced the former Labor government to drop its implacable opposition to light rail and support the GreenWay and light rail project.

"I have been honoured to have been involved in this campaign – I've met with Mayors and community groups, I have lobbied the Minister and attended and spoken at rallies. I have continually raised these issues in Parliament - in speeches, questions to the Minister and questions on notice.

"In its first budget, the O'Farrell Liberal government deferred the extension of the light rail and dumped the GreenWay, in a huge setback for the inner west and the broader active transport network.

"The Government yesterday announced it would begin work on the light rail next month, showing what we can achieve when community commitment joins with local Mayors and Members of Parliament. With this in mind, I will continue to maintain the pressure on the Government to deliver the GreenWay with the light rail project.

"I have previously invited Minister Berejiklian to tour the project and I renew that invitation now: come and see how effectively the GreenWay links with other transport options, encouraging active transport and increasing patronage on the light rail system.

"After over a decade of community campaigning, now is the time for the Government to act and commit to building the GreenWay alongside the light rail corridor."
