Australia's hypersonic engine programme

Australia has been collaborating with the US military in a $54 million programme developing high speed aircraft and missiles capable of flying at more than five times the speed of sound. Hypersonic International Flight Research Experimentation (the HIFiRE program) has been a reality for several years, and facilities have been used in Queensland and the Woomera rocket range in South Australia. Tests of the ramjet (or scramjet) engine at Woomera propelled a missile at over seven times the speed of sound. The US is keen to catch up with Russian techology.

Protection from Government propaganda?

  Attempts to prevent the spread of false information are long overdue. However the Australian Government’s Bill should only be supported if if it covers all the deceptive propaganda spewed out by Government.

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.

God Save the King

 With King Charles III and Queen Camilla in Australia, it's time for some to take a reality check.It is tiresome of the ratbags in the Republican movement to persevere with their flawed campain.   In 1999, Australians went to the polls to decide in a referendum whether to become a republic or to retain the monarchy. The result was clear, On the question of being a republic Australia said NO. Here's a post I put on this blog onSeptember 28 2022 Rabid members of the Australian Rupublic Movement and some politicians keep trying to revive the flawed concept of dumping the monarchy and turning Australia into a republic. The Australian Government talks about holding a referendum to gauge popular support, but before that happens, proponents need to explain what type of republic and how this country will benefit – will it cut the waste of taxpayers dollars? Will it be more democratic? Unless the answer to both those questions in “YES” why spend money on a system that offers no be...
