Senator BIRMINGHAM (South Australia—Minister for Trade, Tourism and Investment and Deputy Leader of the Government in the Senate) (15:04): Both the International Energy Agency and the World Energy Council identify Australia as a potential hydrogen production powerhouse. Opposition senators interjecting— Senator BIRMINGHAM: It's good news, Mr President. That's of course why those opposite are interjecting. They only interject when there's good news from the government or when they are standing up for their union mates—and I suspect we might be hearing quite a bit of irrational noise from them over the hours to come in this place. Opposition senators interjecting— Senator BIRMINGHAM: In relation to hydrogen, the Chief Scientist describes Australia's potential as 'shipping sunshine'. The possibility for us to be able to generate— The PRESIDENT: Senator Cormann, on a point of order? Senator Cormann: I'm reluctant to rise on a point of order, but interjections are disorderly, and there have been a barrage of interjections against Senator Birmingham, who is providing very important information to the Senate and to the Australian people. So I would ask you to call them to order. The PRESIDENT: I have called senators to order on a number of occasions—a handful, in particular, on my left. I will ask senators to restrain themselves for the last minute and a bit of question time. Senator Birmingham to continue. Senator BIRMINGHAM: The opportunities for the hydrogen industry exist across many states. They exist in Senator Rennick's great state of Queensland and they exist across my great state of South Australia. Indeed, in South Australia, the Hydrogen Regulatory Working Group is currently supporting three-megawatt-scale projects in which the South Australian government has co-invested over $40 million alongside the types of investments our government is now scaling up. (Time expired) The PRESIDENT: Senator Rennick, a final supplementary question?
