Russia and China test hypersonic missiles

Both China and Russia are reported to have test fired long range hypersonic missiles capable of flying at five times the speed of sound. The US hopes to develop its own hypersonic missiles within three or four years. The Russian RS-28 Sarmat missile has been designed to outrun anti-missile systems and reach the US within 12 minutes of launch. The missile has been designed to carry nuclear warheads of 40 megatons. The Chinese air to air missile has a range of over 300 km and probably carries thermobaric warheads.

Sand Strategy protects environment and allows resource extraction

  Comments by Ken Henry, Chair of the Australian Climate and Biodiversity Foundation, about Australia's environmental protection laws failing to stop the degradation of our natural environment really hit home.

The Government says that its Communications Legislation Amendment (Combatting Misinformation and Disinformation) Bill 2024  aims  to reduce the spread of seriously harmful misinformation and disinformation on digital communications platforms. However, it is unclear if the Bill will operate in a manner compatible with Australia’s international human rights obligations related to freedom of expression.

Bass Coast Councillors should be personally liable for their mistaken decision

  Bass Coast Shire councillors should be held personally liable for any costs resulting from their decision to reject an application by Heidelberg Materials to widen Stanley Road, Grantville, It seem likely that ratepayers will face a huge bill to defend Councillors’ decision at VCAT. The road widening has long been a requirement of the planning permit previously issued by the Shire and was approved by Shire planning staff as well as DEECA. Rather than make ratepayers foot the bill, councillors who refused the planning application should be personally liable. All councillors other than Jan Thompson, who had the sense to vote for the application should pay every cent.
