Australian Greens Leader Bob Brown says the Gillard government has itself to blame if the Senate delays passage of the mining tax package in coming weeks.

"Where is the government's promised tax cut for small business (from 30% to 29%) due to start in July? It is reasonable to want to see legislation for the small business tax cut before handling the rest of the package," Senator Bob Brown said in Hobart today.

Forestry Tasmania is a rogue agency which is planning to siphon million of dollars from the Intergovernmental Agreement on Tasmania's forests signed by Prime Minister Gillard and Premier Giddings last August, Australian Greens Leader Bob Brown said today.

Australian Greens Leader Bob Brown, speaking to reporters in Canberra, today condemned rogue agency Forestry Tasmania for its treacherous attempt to manipulate the local Indigenous community and further undermine the Intergovernmental Agreement on Forestry.

Other matters raised by journalists included ALP shenanigans and the media inquiry's report due for release tomorrow.

Australian Greens Leader Bob Brown says the 3 month jail sentence imposed on peaceful logging blockader Ali Alishah is in astounding comparison with every Forestry Tasmania officer involved in illegally logging 7 hectares of high conservation value forest in 2007 getting off scot-free.

Australian Greens Leader Bob Brown, speaking to reporters in Hobart, urges the federal government not to delay on heeding the Gonski Review's call for billions of dollars to be injected into the school system.

Senator Brown commented on Premier Giddings' vilification of environmentalists and also described how, amid all the turbulence in federal politics, the Greens are getting on with the job, be it education or protecting the great wild forests of Tasmania.

Premier Lara Giddings claims she has seen tree spikes used by environmentalists.

It is a crass return to the Lennon era of fake vilification of environmentally-aware Tasmanians, Australian Greens Leader Senator Bob Brown said in Hobart today.

“We must all expect better of premiers, especially when, in the same breath, she’s calling for an end to division. 

“For decades, whenever the logging supremos get angry, tree spikes or bombs are brought on to the agenda – it’s a very tawdry ploy,” Senator Brown said.

The outrageous claims by Premier Lara Giddings that environmentalists had been involved in spiking trees in Tasmania should be withdrawn with a clear apology, Greens Leader Bob Brown said in Hobart tonight.

"The environmental movement in Tasmania has been notable for its peaceful protests.

"The Premier's slander is unbecoming of her office as such a lie has no place in debating Tasmania's future," Senator Brown said.

The so-called Minister for the Environment, Tony Burke, today turned on environmentalists in Tasmania and backed the logging of Tasmania's native forests, Australian Greens Leader Bob Brown said.

"He is lambasting Tasmanians who - following a trail of local and foreign loggers - have gone to Tokyo and London to background importers about the iconic forests like the Styx Valley where Mr Burke camped out last year.

"He is converting into an advocate for the chainsaws," Senator Brown said.

The clock is ticking for Tasmania's ancient forests and today people around Australia, and globally, are coming together to stand up for our majestic forests. The actions of one person can be powerful, as is the case with Miranda Gibson.
