Treasury secretary Ken Henry says there is reason to be sceptical about some of the doomsday predictions sparked by the proposed resources tax changes.

In his annual post-budget address to economists, Dr Henry has argued similar predictions have been made in the past by the mining industry and have not eventuated.

He says some of the commentary around the tax has been confused and incorrect, and he has taken aim at the mining industry's outcry.

"In the last four decades numerous predictions have been made of large scale unemployment and the death of manufacturing, decrying deregulation, decrying tariff cuts and decrying mineral booms," he said.

Google has admitted that for the past three years it has wrongly collected information people have sent over unencrypted wi-fi networks.

The issue came to light after German authorities asked to audit the data the company's Street View cars gathered as they took photos viewed on Google maps.

Google said during a review it found it had "been mistakenly collecting samples of payload data from open networks".

The admission will increase concerns about potential privacy breaches.

These snippets could include parts of an email, text or photograph or even the website someone may be viewing.

"Well, obviously oppositions have to do two things. First of all, they have to mount an effective critique of the Government and I think we’ve been doing that. Second, they’ve got to present as a credible alternative, they’ve got to convince people that life would be different and better if there was a change and that’s what we’re doing, I hope"

The US government has demanded immediate clarification from BP over its commitment to pay for costs caused by the oil spill in the Gulf of Mexico.

The Obama administration said it wanted to be sure BP would honour commitments not to limit payments for damages to a US statutory cap of $75m (£50m).

Meanwhile, BP says oil dispersants applied at the source of the leak on Friday have begun to take effect.

Mississippi has become the third US state to have oil wash up on its coast.

The New South Wales Government has announced it will block the proposed Bickham coal mine in the Upper Hunter Valley near Scone.

The mine has been strongly opposed by locals in the area, who say their farming activities and horse studs would be adversely affected for little gain.

Premier Kristina Keneally says the project was assessed on its merits and they did not stack up.

She says she will amend government policy to stop similar proposals in the future.

"The Government will not allow the Bickham coal mine proposal to proceed," she said.

The Federal Government has fended off accusations its plan to get the budget back into the black is banking too heavily on a continuing mining boom and big taxes.

Treasurer Wayne Swan unveiled his "no-frills" 2010-11 budget last night, his pre-election pitch to voters focusing on spending restraint and conservative economic management.

The forecasts paint a vastly different picture for Australia's economic prospects than what was predicted just a year ago and the Government says its strict fiscal controls are a major driver of the improvement.

In his book, “Heaven + Earth. Global warming: the missing science”, Professor Ian Plimer from the University of Adelaide questions the science of human-induced climate change. A range of Australian scientists respond to the book.

But first a word from Gus.

I find it quite extraordinary that a serious scientist, atheist and sceptic, would use the word "heaven" in the title of his work. It's perverse. Being a miner as well as a professor, Ian Plimer would have massive conflict of interests should he subscribe to the "global warming" theory. Thus he does not.

TONY Abbott is under pressure to justify a claim to primary school students that it was considerably warmer when Jesus was alive than it is today.

The Opposition Leader urged year 5 and 6 students at Trinity Gardens Primary School in Adelaide to be sceptical about the human contribution to climate change, saying it was an open question.

During a question-and-answer session on Friday, Mr Abbott said that it was warmer ''at the time of Julius Caesar and Jesus of Nazareth'' than now.

Talk show host Ellen DeGeneres has become the latest casualty of the hyper-vigilant image police at Apple HQ.

DeGeneres apologised on air this week for a spoof iPhone commercial that she ran on her daily talk show poking fun at her inability to send text messages from an iPhone.

She said the spoof did not impress Apple when it aired this week and that she had since been contacted by the company.

Sydney has experienced its fifth warmest April on record with a month of balmy nights and little rain.

But don't put away the warm clothes just yet with predictions that winter is on the way; it's just running a little late.

The average April minimum temperature was 1 degree above the average of 16 degrees. Combined with high humidity and little wind, temperatures rose.

The US Coast Guard is investigating reports that oil has started washing ashore on the Gulf Coast from a leaking offshore well.

Up to 5,000 barrels of oil a day are thought to be spilling into the water after last week's explosion on a BP-operated rig, which then sank.

President Barack Obama has pledged "every single available resource" to help.

The US navy has been deployed to help avert a looming environmental disaster.

The US Coast Guard said it had sent investigators to confirm whether crude oil had begun to wash up on parts of the Louisiana shoreline.

'Mind-boggling'

AS NEWS spread that cigarette prices were on their way up, a tobacconist in St Marys saw a few more faces than usual.

''We really got busy'' in the afternoon, said the manager of the tobacconist Free Choice, Harshad Vekaria. ''People started knowing then.''

From midnight last night, the government increased tobacco taxes by 25 per cent, adding about $2.16 to a pack of 30 cigarettes.

Over four years the government expects this will generate an extra $5 billion, which it has pledged to invest in hospitals.
