Greens Treasury spokesperson and Senator for Tasmania, Peter Whish-Wilson, says that Barnaby Joyce and Scott Morrison need to take responsibility for the backpacker tax mess and come to Tasmania immediately to see first-hand the impact this tax will have on the Tasmanian economy.

Senator Whish-Wilson said, "This Government has made it clear its priority for this 45th parliament is so called 'deficit repair,' not the needs of small Tasmanian agricultural businesses.

The Australian Greens say the Liberals are set to deliver a Budget that will grow inequality by
including company tax cuts and income tax cuts for above average income earners.

"This Budget, like this Prime Minister, is shaping up to be a huge disappointment," said Greens Leader Richard Di Natale.

"Malcolm Turnbull came in and said everything was on the table, but now he and his Treasurer are serving up the same tired old dishes as Tony Abbott.

The Senate has just voted in favour of a Greens motion to launch an inquiry into corporate tax evasion, in the lead-up to the G20 summit.

"On the same day that Labor has facilitated some of Joe Hockey's cruel budget cuts, the Greens have launched an inquiry to end the age of entitlement for the big end of town," said Greens Leader Christine Milne.

"Instead of pulling safety nets out from under people in our community who most need support, the Abbott government should look for ways to raise revenue from those who can afford to pay.

Greens Leader Christine Milne says she will this week move for a Senate inquiry into corporate tax evasion in Australia.

"In Tony Abbott and Joe Hockey's Australia the real leaners are the big corporations. The big end of town is not paying anywhere near the amount of tax it should be paying," Senator Milne said.

"Instead Tony Abbott is trying to raise revenue from the poor, the sick and the young. This is wrong.

"If the Abbott government wants to raise revenue for its phoney budget emergency they need to crack down on corporate tax evasion.

Greens Leader Christine Milne says the Abbott government is attempting to trick the states into talking about the GST, to distract from his brutal budget and the opportunities that still exist to raise revenue from his big business mates.

"My message to the states is: don't fall for Tony Abbott's GST ploy. The Prime Minister is trying to fool you and distract the community from his cruel budget cuts," Greens Leader Christine Milne said.
